The D.O.C. collaborated with gangsta rap group N.W.A–where he co-wrote many of their releases–as well as Eazy-E's solo debut album Eazy-Duz-It.  He was one of the founders of Death Row Records along with Dr. Dre and Suge Knight.

In 1989, he released his debut album, No One Can Do It Better, which reached number-one on the US Top R&B/Hip-Hop Albums chart for two weeks and spawned two number one hits on the Hot Rap Songs chart: "It's Funky Enough" and "The D.O.C. & The Doctor". The album went platinum five years after its release. In late 1989, months after the release of No One Can Do It Better, The D.O.C. suffered a serious car crash that resulted in the crushing of his larynx, permanently changing his voice.

After the crash that changed the direction of his musical career D.O.C. experienced a depressing period in his life. It wasn't until he began dating Erykah Badu that he was able to find direction and guidance in his life again--all thanks given to Erykah Badu. Their relationship resulted in the birth of his daughter Puma and a friendship and spiritual bond between Erykah Badu and himself that still stands to this day.

The D.O.C. is still considered one of the greatest MCs of all time, his album garnered the coveted 5 mic award and Dr. Dre still relies on D.O.C for. musical input. It is safe to say D.O.C. is still  Ballin. Tune in to the Ballin Podcast to get the full scoop.
