Even after a near-fatal accident reduced his voice to a raspy whipster, derailing his promising solo career, The D.O.C. made an impact as the pen behind many Dre's verses on The Chronic. He also appears on the skit "The $20 Sack Pyramid." In 2011, The D.O.C. was reportedly preparing to get surgery to restore his voice and prepping to release his fourth solo album, but he's been out of the news ever since.
