The World Class Wreckin' Cru was a 1980s Electro-hop group from Compton, California formed by the Eve After Dark nightclub owner and established DJ Alonzo Williams. Other members of the fluctuating line-up included DJ Yella, Dr. Dre, Shakespeare, Cli-N-Tel, and Mona Lisa Young (Dre's sister). Dr. Dre and DJ Yella would go on to achieve fame as members of N.W.A.. Fila Fresh Crew's Dr. Rock was also an early member of the World Class Wreckin' Cru.
The group were originally known as The Wreckin' Cru and used that name when the groups first song was produced called "Slice" performed by DJ Yella and Cli-N-Tel. Although when the World Olympics were coming to Los Angeles during 1984, Lonzo decided to change the groups name to the World Class Wreckin' Cru.
They were managed by Jerry Heller, who also managed Egyptian Lover and LA Dream Team. Heller would later become part of the gangsta rap scene on the west coast, forming Ruthless Records with Eazy-E, and helping launch the careers of several rap artists. Jerry Heller and Eazy-E were introduced through Lonzo Williams in the Eve After Dark nightclub.
In 1987, the group hit the national charts with "Turn Off the Lights", featuring vocals by Michel'le. However, by this time Dr. Dre and DJ Yella had left to join Eazy-E and Ice Cube in N.W.A. Alonzo Williams went on to briefly front a new group with a similar name, World Class Wreckin' Kru.
