Gaga came to prominence following the release of her debut studio album The Fame (2008), which was critically praised and noted for its influences of synthpop music. Its first two singles, "Just Dance" and "Poker Face", were number-one singles and the album itself reached number one on nine record charts worldwide. Gaga embarked on the Fame Ball Tour in order to promote the album. Following it, Gaga released an extended play, The Fame Monster, which spawned international number-one singles "Bad Romance", "Telephone" and "Alejandro". In order to promote the album, Gaga embarked on the eighteen-month long Monster Ball Tour, eventually becoming one of the highest-grossing concert tours of all time. Her album Born This Way was later released, topping the charts on several major markets and spawning international chart-topping singles "Born This Way", "Judas" and "The Edge of Glory". Aside from being a recording artist, Gaga has also involved herself with humanitarian causes and LGBT activism.
Lady Gaga was born Stefani Joanne Angelina Germanotta on March 28, 1986, in New York City. The first child of Cynthia (née Bissett) and Joseph Germanotta, an internet entrepreneur, Gaga – of Italian and more distant French-Canadian ancestry – has one sister called Natali who was born in 1992. Raised as a Roman Catholic left-handed Gaga began learning to play piano at the age of 4, went on to write her first piano ballad at 13, and started to perform at open mike nights by the age of 14. While Gaga spent much of her childhood in the family's home in Manhattan's Upper West Side, she attended the Convent of the Sacred Heart, a private all-girls Roman Catholic school on Manhattan's Upper East Side, from the age of 11. Despite her seemingly affluent upbringing, Gaga has stressed that she did not come from a wealthy background, stating that her parents "both came from lower-class families, so we've worked for everything—my mother worked eight to eight out of the house, in telecommunications, and so did my father." She described her academic life in high school as "very dedicated, very studious, very disciplined" but also "a bit insecure" as she told in an interview, "I used to get made fun of for being either too provocative or too eccentric, so I started to tone it down. I didn't fit in, and I felt like a freak." Acquaintances dispute that she did not fit in at school. "She had a core group of friends; she was a good student. She liked boys a lot, but singing was No. 1," recalled a former high school classmate.
An avid actor in high school musicals, Gaga portrayed the lead roles of Adelaide in Guys and Dolls and Philia in A Funny Thing Happened on the Way to the Forum. She also appeared in a very small role as a mischievous classmate in the television drama series The Sopranos in a 2001 episode titled "The Telltale Moozadell". At age 16, she began to sing and play in front of live audiences and unsuccessfully auditioned for parts in New York shows. When her time at the Convent of the Sacred Heart came to an end, her mother encouraged her to apply to New York University (NYU) to study with the Collaborative Arts Project 21 (CAP21), a faculty of the Tisch School of the Arts. Aged 17, Gaga gained early admission and lived in a NYU dorm on 11th Street. With CAP21, she studied musical theatre and sharpened her songwriting skills. She also composed essays and analytical papers on art, religion, social issues and politics including a thesis on pop artists Spencer Tunick and Damien Hirst; such research prepared her for her future career focus in "music, art, sex and celebrity." Gaga felt that she was more creative than some of her classmates. "Once you learn how to think about art, you can teach yourself," she said. Being part of such a prestigious performance course, Gaga tried out for and won auditions while at CAP21, including the part of an unsuspecting diner customer where MTV's Boiling Points – a prank reality television show – was being filmed. Notwithstanding these achievements, by the second semester of her sophomore year, she withdrew from the school to focus on her musical career. Her father agreed to pay her rent for a year, on the condition that she re-enroll at Tisch if she was unsuccessful. "I left my entire family, got the cheapest apartment I could find, and ate shit until somebody would listen," she remembers.
Settled in a small apartment on Rivington Street towards the summer of 2005, Gaga recorded a couple of songs with hip-hop singer Grandmaster Melle Mel, for an audio book accompanying the children's book The Portal in the Park, by Cricket Casey. She also began a band called the Stefani Germanotta Band (SGBand) with some friends from NYU – guitarist Calvin Pia, bassist Eli Silverman and drummer Alex Beckham – in September of that year. The band played a mixture of songs: some self-penned alongside classic rock numbers like Led Zeppelin's "D'yer Mak'er". Playing in Lower East Side bars like The Bitter End and the Mercury Lounge, the band developed a small fan base and caught the eye of music producer Joe Vulpis. Soon after arranging time in Vulpis' studio in the months that followed, SGBand were selling their extended plays Words and Red and Blue at gigs around New York while becoming a local fixture of the downtown Lower East Side club scene.
SGBand reached their career peak at the 2006 Songwriters Hall of Fame New Songwriters Showcase at The Cutting Room in June where Wendy Starland, a singer and model, appeared as a talent scout for music producer Rob Fusari. Starland informed Fusari – who was searching for a female singer to front a new band – of Gaga's ability and contacted her. By this time, SGBand had disbanded; Gaga traveled daily to New Jersey to work on songs she had written and compose new material with the music producer. While in collaboration, Fusari compared some of her vocal harmonies to those of Freddie Mercury, lead singer of Queen. It was Fusari who helped create the moniker Gaga after the Queen song "Radio Ga Ga". Gaga was in the process of trying to come up with a stage name when she received a text message from Fusari that read "Lady Gaga." He explained, "Every day, when Stef came to the studio, instead of saying hello, I would start singing 'Radio Ga Ga'. That was her entrance song" and that the text message was the result of a predictive text glitch that changed "radio" to "lady". She texted back, "That's it," and declared, "Don't ever call me Stefani again." The New York Post, however, has reported that this story is incorrect, and that the name resulted from a marketing meeting.
Although the musical relationship between Fusari and Gaga was unsuccessful at first, the pair soon set up a company titled Team Lovechild in which they recorded and produced electropop tracks and sent them to music industry bosses. Joshua Sarubin, the head of A&R at Def Jam Recordings, responded positively and vied for the record company to take a chance on her "unusual and provocative" performance. After having his boss Antonio "L.A." Reid in agreement, Gaga was signed to Def Jam in September 2006 with the intention of having an album ready in nine months. However, she was dropped by the label after only three months. Devastated, Gaga returned to the solace of the family home for Christmas and the nightlife culture of the Lower East Side. She became increasingly experimental: fascinating herself with emerging neo-burlesque shows, go-go dancing at bars dressed in little more than a bikini in addition to experimenting with drugs. "I was onstage in a thong, with a fringe hanging over my ass thinking that had covered it, lighting hairsprays on fire, go-go dancing to Black Sabbath and singing songs about oral sex. The kids would scream and cheer and then we'd all go grab a beer. It represented freedom to me. I went to a Catholic school but it was on the New York underground that I found myself." It was then when she became romantically involved with a heavy metal drummer in a relationship and break-up she likened to the musical film Grease: "I was his Sandy, and he was my Danny, and I just broke." He later became an inspiration behind some of her later songs.
Her father, however, did not understand the reason behind her drug intake and could not look at her for several months. During this time, she met performance artist Lady Starlight, who helped mold her on-stage persona. Starlight explained that, upon their first meeting, Gaga wanted to perform with her to songs she had recorded with Fusari. Like SGBand, the pair soon began playing gigs at many of the downtown club venues like the Mercury Lounge, The Bitter End, and the Rockwood Music Hall. Their live performance art piece was known as "Lady Gaga and the Starlight Revue" and, billed as "The Ultimate Pop Burlesque Rockshow", was a low-fi tribute to 1970s variety acts. Soon after, the two were invited to play at the 2007 Lollapalooza music festival in August that year. The show was critically acclaimed, and their performance received positive reviews. Having initially focused on avant-garde electronic dance music, Gaga had found her musical niche when she began to incorporate pop melodies and the glam rock of David Bowie and Queen into her music. While Gaga and Starlight were busy performing, producer Rob Fusari continued to work on the songs he had created with Gaga. Fusari sent these songs to his friend, producer and record executive Vincent Herbert. Herbert was quick to sign her to his label Streamline Records, an imprint of Interscope Records, upon its establishment in 2007. Gaga later credited Herbert as the man who discovered her, adding "I really feel like we made pop history, and we're gonna keep going." Having already served as an apprentice songwriter under an internship at Famous Music Publishing, which was later acquired by Sony/ATV Music Publishing, Gaga subsequently struck a music publishing deal with Sony/ATV. As a result, she was hired to write songs for Britney Spears and labelmates New Kids on the Block, Fergie, and the Pussycat Dolls. While Gaga was writing at Interscope, singer-songwriter Akon recognized her vocal abilities when she sang a reference vocal for one of his tracks in studio. He then convinced Interscope-Geffen-A&M Chairman and CEO Jimmy Iovine to form a joint deal by having her also sign with his own label Kon Live Distribution, making her his "franchise player." As 2007 came to a close, her former management company introduced her to songwriter and producer RedOne, whom they also managed. The first song she produced with RedOne was "Boys Boys Boys", a mash-up inspired by Mötley Crüe's "Girls, Girls, Girls" and AC/DC's "T.N.T.". Gaga continued her collaboration with RedOne in the recording studio for a week on her debut album and also joined the roster of Cherrytree Records, an Interscope imprint established by producer and songwriter Martin Kierszenbaum, after co-writing four songs with Kierszenbaum including the singles "Christmas Tree" and "Eh, Eh (Nothing Else I Can Say)". Despite her secure record deal, she admitted that there was fear about her being too "racy", "dance-orientated" and "underground" for the mainstream market. She responded, "My name is Lady Gaga, I've been on the music scene for years, and I'm telling you, this is what's next." By 2008, Gaga had relocated to Los Angeles, where she worked extensively with her record label to complete her debut album in addition to setting up her own creative team – modeled on Andy Warhol's Factory – Haus of Gaga. Intensive work continued on the album, combining genres "from Def Leppard drums and hand claps to metal drums on urban tracks" while drawing inspiration from 1980s synthpop and incorporating dance music with clear hooks.
