A glamorously gaudy, self-made, post-modern diva stitched together from elements of Madonna, David Bowie, and Freddie Mercury, Lady Gaga was the first millennial superstar. Mastering the constant connection of the Internet era, Gaga generated countless mini-sensations with her style, her videos, and her music, cultivating a devoted audience she dubbed "Little Monsters." But it wasn't just a cult that turned her 2008 manifesto The Fame into a self-fulfilling prophecy: Gaga crossed over into the mainstream, ushering out one pop epoch and kick-starting a new one, quickly making such turn-of-the-century stars as Christina Aguilera and Britney Spears seem old-fashioned. It was quite a trick for any artist to pull off, but especially impressive for one who specialized in repurposing the past (particularly the '80s) for present use, creating sustainable pop for a digital world. Gaga's fame soon extended beyond music: she received accolades for her 2015 role in American Horror Story: Hotel and her Oscar-nominated turn in Bradley Cooper's 2018 remake of A Star Is Born. Within two years, she returned to the top of the Billboard 200 with Chromatica, then notched another Top Ten and Grammy-win with her second standards album, Love for Sale. She also scored a top 40 hit with "Hold My Hand" off the Top Gun: Maverick soundtrack in 2022, before joining the Rolling Stones for 2023's "Sweet Sounds of Heaven."

Perhaps unsurprisingly given her flair for grand gestures, Lady Gaga has deep roots in drama. Born Stefani Germanotta on March 28, 1986, the future Gaga played piano as a child and pursued musical theater in high school, regularly auditioning for New York-based television shows, notably landing a background role for a 2001 episode of The Sopranos. At the age of 17 she enrolled at New York University's Tisch School of the Arts in their Collaborative Arts Project 21. As she studied, she continued to eke her way into show biz, winding up with an appearance on MTV's short-lived post-Punk'd reality show Boiling Points in 2005. Not long afterward, she left school so she could concentrate on her music, fronting a band called SGBand, which released two EPs prior to splitting. Germanotta then teamed with producer Rob Fusari, a collaboration that produced not only her stage name Lady Gaga, but recordings that led to her signing with Def Jam in the fall of 2006.

Her association with Def Jam was short-lived: the label dropped her early in 2007. Gaga rebounded by working with performance artist Lady Starlight, the two developing the Lady Gaga & the Starlight Revue, a tongue-in-cheek neo-burlesque act that gained positive press and proved to be her last stop before signing with Interscope later in 2007. While at Interscope, she created a bond with Akon, who convinced Interscope head Jimmy Iovine to have her co-sign with his Kon Live imprint, and Gaga began working with producer/songwriter RedOne, a union that led to the songs that would bring her fame: "Just Dance," "LoveGame," and "Poker Face." These songs formed the foundation of The Fame, the debut album that appeared in August 2008.

Initially, Lady Gaga had greater success in Europe, thanks in large part to the "Just Dance" single, which earned club play in the U.S. and chart placement in other territories. Gaga's march toward the top of the American chart was slow but "Just Dance" reached the peak position in January 2009, followed swiftly by "Poker Face," the single that firmly pushed her into the mainstream, its popularity growing so large it often functioned as a punch line on TV in addition to winning a Grammy for Best Dance Recording. "LoveGame" and "Paparazzi" also appeared as singles before Gaga released The Fame Monster in time for the holiday season of 2009. The mini-LP, available separately and as a package with The Fame, contained the single "Bad Romance," whose popularity soon rivaled "Poker Face" and helped kick-start a stellar year for Gaga in 2010. That year, the hit singles "Bad Romance," "Alejandro," and the Beyoncé duet "Telephone," along with the successful Monster Ball Tour, put Lady Gaga front and center with the public as she worked on her sophomore album, announcing its May release on New Year's Day 2011.

The steady march to the summer unveiling of Born This Way was preceded by the release of three singles: "Born This Way," "Judas," and "The Edge of Glory." All of them reached the Top Ten, and the empowerment anthem "Born This Way" hit number one soon after its release in February 2011. The accompanying album arrived to mixed reviews, but it eventually reached double-platinum status and produced subsequent hits with the Top Ten "You and I" as well as a Top 40 entry for "Marry the Night." A full remix of the album, naturally called Born This Way: The Remix, appeared at the end of the year, as did a holiday television special called A Very Gaga Thanksgiving and an accompanying EP, A Very Gaga Holiday.

Gaga continued to promote Born This Way throughout 2012, appearing at various star-studded events and on television programs while continuing her international tour. The tour came to a halt in February of 2013, when she announced that she needed hip surgery to repair a labral tear. As she was healing, she worked on her third album, Artpop. Preceded by the Top Ten single "Applause" and the Top 15 follow-up "Do What U Want" (the latter a duet with R. Kelly), Artpop was released in early November 2013. The album explored familiar themes of fame, love, and empowerment. It debuted at number one in several countries, including the U.S.

The release of Artpop coincided with an announcement that Gaga had parted company with Troy Carter, her manager of five years. Then, shortly after she embarked on the ArtRave tour in May 2014, it was revealed that Bobby Campbell -- her new manager -- had signed them both up to Artist Nation, the artist management division of Live Nation Entertainment. That same year, Gaga worked in collaboration with fellow New Yorker Tony Bennett on an album of jazz standards titled Cheek to Cheek, which was issued in September. Cheek to Cheek provided a jolt to Gaga's career. The album debuted at number one on Billboard's Top 200 and earned the Grammy Award for Best Traditional Pop Album, its success opening the door to other snazzy show biz gigs. First, she sang a tribute to The Sound of Music at the 2015 Academy Awards and, a year later, she was nominated for a Best Original Song Oscar for "Until It Happens to You," the tune she co-wrote with Diane Warren for the documentary The Hunting Ground. Gaga was also cast as a lead in the 2015-2016 season of American Horror Story, winning a Golden Globe for her portrayal of Elizabeth.

She returned with new music on 2016's Joanne, which was inspired by her late aunt of the same name. Drawing on glam rock, disco, and folk, as well as dance-pop, the album featured an impressive list of collaborators, including Mark Ronson, Nile Rodgers, Father John Misty, Josh Homme, Florence Welsh, Tame Impala's Kevin Parker, and Beck. Featuring the singles "Perfect Illusion," "John Wayne," and "Million Reasons," the album debuted at the top of the Billboard 200 but quickly lost traction on the charts. It wasn't until February of 2017 that the success of her Super Bowl halftime show would set Joanne on the comeback trajectory. In addition to returning The Fame, Born This Way, and Artpop to the charts, the momentum from her performance landed Joanne at number two and "Million Reasons" at number four on the Hot 100. Before embarking on the Joanne World Tour, she issued the standalone single "The Cure" and the documentary Gaga: Five Foot Two, which partially focused on chronic physical ailments that would eventually cause the cancellation of the final stops of the world tour.

In 2018, Gaga made the leap to the silver screen by starring alongside Bradley Cooper in his remake of the classic Hollywood fable A Star Is Born. Upon its release in October, the soundtrack to the film debuted at the top of the Billboard and U.K. charts, while the film itself turned into a commercial and critical hit. Lady Gaga earned two Academy Award nominations for A Star Is Born: a nod for Best Actress and as a co-composer of "Shallow," which was nominated for, and won, Best Original Song. After its win, the song reached number one on the Billboard charts. In 2020, she won the Best Song Written for Visual Media Grammy Award for the A Star Is Born track "I'll Never Love Again," which she co-wrote with Natalie Hemby, Hillary Lindsey, and Aaron Raitiere.

Gaga's Grammy win arrived as she ramped up the release cycle for Chromatica, her sixth LP. A return to glitzy dance-pop, Chromatica arrived in May 2020, preceded by the singles "Stupid Love" and "Rain on Me," the latter a duet with Ariana Grande that debuted at number one on the Hot 100. Also featuring appearances by BlackPink and Elton John, the album continued Gaga's streak of number one entries on the Billboard 200. A remix album, Dawn of Chromatica, arrived in 2021 and featured contributions by Arca, Rina Sawayama, Charli XCX, and many more. That same year, Gaga remained in the spotlight, singing the national anthem at Joe Biden's presidential inauguration ceremony, joining the cast of Ridley Scott's House of Gucci, and celebrating the tenth anniversary of Born This Way with an EP dubbed Born This Way Reimagined, which showcased covers by Kylie Minogue, Big Freedia, Orville Peck, Years & Years, and others. Also that year, she reunited with Tony Bennett for a follow-up to their 2014 collaboration, a Cole Porter tribute dubbed Love for Sale, which won the Grammy for Best Traditional Pop Vocal Album.

The following May, Gaga contributed a classic arena power balled called "Hold My Hand" to the Top Gun sequel, Top Gun: Maverick. She performed the song at the 95th Academy Awards Ceremony where it was nominated for Best Original Song. Following her successful The Chromatica Ball stadium tour, Gaga again captured the zeitgeist when a remix of her song "Bloody Mary" was featured in the Netflix show Wednesday. As a result, the song went viral on social media and returned to the Billboard top 40. In 2023, she joined Stevie Wonder on the Rolling Stones' song "Sweet Sounds of Heaven" off their Hackney Diamonds album.

2024 was no less busy for Gaga. In addition to starring as Harley Quinn in the film Joker: Folie à Deux, she also performed during the opening ceremony of the Paris Summer Olympics. Her eighth studio album was also announced, with the first taste arriving that August in the form of "Die With a Smile," a duet with fellow Vegas residency singer Bruno Mars. ~ Stephen Thomas Erlewine

A born entertainer with a stage name ideal for a showman, Bruno Mars is not only a charismatic performer but also a songwriter, producer, multi-instrumentalist, and all-around studio collaborator whose Grammy nominations and awards have recognized his full range of talent. Putting a modern pop twist on styles such as early rock & roll and R&B, new wave, and reggae, Mars came to prominence in 2010, the year his name appeared at or near the top of the Billboard Hot 100 with B.o.B's "Nothin' on You," his own "Just the Way You Are," and CeeLo Green's "Fuck You" -- all three of which he had a hand in writing and producing. Those hits, along with Mars' multi-platinum debut album Doo-Wops & Hooligans, led to a total of 13 Grammy nominations and a win for Male Pop Vocal Performance. Mars was only getting started. His 2012 return Unorthodox Jukebox, chart-topping Mark Ronson collaboration "Uptown Funk," and production for Adele's 25, followed by his 2016-issued third album 24K Magic, combined for ten Grammys including wins in three of the Big Four categories. Having contemporized several shades of funk, mid-'80s pop, and new jack swing on 24K Magic, Mars then teamed with touring partner Anderson .Paak to record a set of knowing retro-soul under the name Silk Sonic. Their 2021 LP An Evening with Silk Sonic became Mars' fourth platinum album with the number one pop hit "Leave the Door Open" alone taking four Grammys. The duo's 2022 cover of Con Funk Shun's "Love's Train," fronted by Mars with typically raspy conviction, has since become an R&B radio staple.

Born Peter Hernandez in 1985 in Honolulu, Hawaii, Mars kicked off his career at the age of four by fronting his uncle's band, becoming Oahu's youngest Elvis impersonator in the process. Ten years later, he was impersonating the King of Pop, Michael Jackson, as part of the Legends in Concert show. After graduating high school in 2003, he took his uncle's advice and moved to California to pursue a music career. He eventually met songwriter Philip Lawrence, who convinced Mars to try his hand at writing songs for other artists. The two dubbed themselves the Smeezingtons and co-wrote Brandy's "Long Distance." The duo scored their first number one hit in 2009, when they co-authored Flo Rida's international smash "Right Round."

By 2010, Mars seemed to be everywhere: singing alongside B.o.B on the chart-topping "Nothin' on You," co-writing "Billionaire," and collaborating with CeeLo Green on the Grammy-nominated hit "Fuck You." He also began issuing his own material, starting with the May 2010 release of his first EP, It's Better If You Don't Understand. Doo-Wops & Hooligans, his full-length debut, appeared later that year and quickly produced a number one single, "Just the Way You Are." He hit number one again with "Grenade" and remained in the Top Ten with "The Lazy Song" and "It Will Rain." In 2012, Mars both hosted and performed as a musical guest on Saturday Night Live, debuting tracks from his upcoming album.

That record, the genre-jumping effort Unorthodox Jukebox, was released later in the year and featured the chart-topping single "Locked Out of Heaven," along with production from Mark Ronson, Diplo, and others. "Locked Out of Heaven" topped the Hot 100, and the album reached number two in the U.S. The second single, "When I Was Your Man," also hit number one. Unorthodox Jukebox later won a Grammy Award for Best Pop Vocal Album. All that success made Mars a natural for one of the world's most prestigious gigs, the half-time show for Super Bowl XLVIII, where he performed with Red Hot Chili Peppers in 2014. Mars later fronted Mark Ronson's "Uptown Funk," a song he co-wrote that was among the most popular singles of that year. It topped charts around the globe (becoming his sixth number one) and took home several Grammy Awards, including Record of the Year.

In 2016, Mars returned with another funk-flavored hit, "24K Magic," and its parent album of the same title. Influenced by soul, funk, and '90s R&B, 24K Magic peaked at number two on the Billboard 200 and produced Mars' seventh chart-topper, "That's What I Like," as well as "Finesse" with rapper Cardi B and "Versace on the Floor," which was also released as a remix by David Guetta. The album took home the Grammy Award for Best Engineered Album, Non-Classical. In February 2019, Mars again collaborated with Cardi B on the track "Please Me," which landed at number three on the Billboard Hot 100. That July, he paired with Ed Sheeran and Chris Stapleton on the song "Blow."

In early 2021, Mars teamed with Anderson .Paak -- who opened the European leg of the 24K Magic World Tour -- as Silk Sonic. After releasing their first single, "Leave the Door Open," in March, the duo made their television debut with a performance at the 2021 Grammy Awards. A year later, the pair dominated the 2022 Grammys ceremony, taking home awards for Record of the Year, Song of the Year, Best R&B Performance, and Best R&B Song for "Leave the Door Open" from their global Top Ten debut An Evening with Silk Sonic. Also in 2022, the duo returned to the airwaves with a faithful cover of Con Funk Shun's 1982 deep quiet storm classic "Love's Train." ~ David Jeffries & Andy Kellman
