Dr. Luke’s career began ‘live from New York’ as a member of the SNL band. He went from playing guitar to playing a major role in the success of many of today’s big artists, including Katy Perry, Ke$ha and Adam Lambert. It’s no surprise that Doc is up for two Grammys this year—Producer Of The Year, Non-Classical and Album of the Year (Teenage Dream by Katy Perry). [Photo: Billboard.com]
