D.O.C. also appeared on a skit called "The $20 Sack Pyramid" on Dr. Dre's 1992 album The Chronic.After Fila Fresh Crew split up in 1988, The D.O.C. went on to pursue a successful solo career. 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. Months after the release of No One Can Do It Better, The D.O.C. almost died when a car accident resulted in crushing his larynx, permanently changing his voice.
