Andre Manuel, a disc jockey and record producer called The Unknown DJ or DJ Unknown, was a pioneer in the Los Angeles area's 1980s music scene, moving from electro funk and electro rap to gangsta rap. Now a legend of West Coast rap, he worked with rapper Ice-T in the early 1980s, then with Alonzo "Grandmaster Lonzo" Williams, and with MC Eiht's group Compton's Most Wanted in the early 1990s.
