On Friday, Dr. Dre will drop Compton: The Soundtrack, his first project since 1999's 2001. He's kept busy in the 16 years inbetween, executive producing hip hop classics like Eminem's Marshall Mathers LP, 50 Cent's Get Rich Or Die Tryin', & The Game's The Documentary and contributing to the making of hundreds of other projects. He hasn't done it all by himself -- credit must be given to his frequent co-producers, such as Mark Batson, Mel-Man, & Mike Elizando -- but Dr. Dre has earned his status as one of the greatest music producers of all time.
