He has produced albums for and overseen the careers of many rappers, including The D.O.C., Snoop Dogg, Eminem, Xzibit, Knoc-turn'al, 50 Cent, The Game and Kendrick Lamar.

Dre began his career as a member of the World Class Wreckin' Cru and later found fame with the influential gangsta rap group N.W.A with Eazy-E, Ice Cube, MC Ren, and DJ Yella, which popularized the use of explicit lyrics in rap to detail the violence of street life. His 1992 solo debut The Chronic, released under Death Row Records, led him to become one of the best-selling American performing artists of 1993 and to win a Grammy Award for the single "Let Me Ride". That same year he produced Death Row labelmate Snoop Dogg's quadruple platinum debut Doggystyle, and even molded artists into top-notch producers such as his step-brother Warren G, which led to his multi-platinum debut Regulate...G Funk Era in 1994, and Snoop Dogg's cousin Daz Dillinger which led to the double platinum debut album Dogg Food by Tha Dogg Pound in 1995. In 1996, he left Death Row Records to establish his own label, Aftermath Entertainment. He produced a compilation album titled Dr. Dre Presents the Aftermath in 1996, and released a solo album titled 2001 in 1999. During the 2000s, he focused on production for other artists, while occasionally contributing vocals to songs.
