World Class Wreckin' Cru was an American electro group, during the 1980s in the Los Angeles area, that contributed to rap's development. Two of its members, Dr. Dre and DJ Yella, attained greater fame as members of N.W.A, which pioneered gangsta rap. A song by the Cru had also featured R&B singer Michel'le.

Andre Romell Young, known professionally as Dr. Dre, is an American record producer and rapper. He is the founder and CEO of Aftermath Entertainment and Beats Electronics, and co-founded and was the president of Death Row Records. Dre began his career as a member of the World Class Wreckin' Cru in 1985, and later found fame with the gangsta rap group N.W.A. The group popularized explicit lyrics in hip hop to detail the violence of street life. During the early 1990s, Dre was credited as a key figure in the crafting and popularization of West Coast G-funk, a subgenre of hip hop characterized by a synthesizer foundation and slow, heavy production.
