Lady Gaga, Stefani Joanne Angelina Germanotta

• 2005–07: Career beginnings
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, along with 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 beneath a New Jersey liquor store 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.
While at the peak of their career, SGBand performed at the 2006 Songwriters Hall of Fame New Songwriters Showcase at The Cutting Room in June where Wendy Starland, a singing model, appeared as a talent scout for music producer Rob Fusari who was searching for a female singer to front a new band. After Starland had informed Fusari of Gaga's ability, he contacted her. By this time, SGBand had grown apart and Gaga left to work with the music producer in New Jersey where she would travel daily to work on songs she had written and compose new material. While in collaboration, Fusari compared some of her vocal harmonies to those of Freddie Mercury, lead singer of Queen. It was Fusari who helped created 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. Lady Gaga was actually a glitch; I typed 'Radio Ga Ga' in a text and it did an autocorrect so somehow 'Radio' got changed to 'Lady'. She texted me back, "That's it." After that day, she was Lady Gaga. She's like, "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 electro-beat pop 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 the family home for Christmas as well as the nightlife culture of the Lower East Side. Becoming fascinated with some of the emerging neo-burlesque shows, Gaga began Go-Go dancing in bars dressed in little more than bikini. She began experimenting with drugs in addition to performing in many shows. "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."
