World Class Wreckin' Cru is an electro group, best known for its contributions to early rap and its association with Dr. Dre.

World Class Wreckin' Cru debuted in a club owned by one of the early West Coast DJs, Alonzo Williams. Before he opened "Eve After Dark" in 1979, Alonzo transformed from popping and locking to DJ dances under the name of Disco Construction, named after funk group Brass Construction. Seeing the popularity of this new craze, he entered the market of running nightclub performances. The club opened with Detroit-born Andre Manuel aka Unknown DJ directing the music program whose main influence derived from an east coast flavour, Soulsonic Force, Orbit and Scorpio.
As the 1980s arrived, so did electronic funk, sampling drum beats fused with old school rap format. Disco Construction changed its name into Wreckin' Cru. Lonzo hired local DJs Antoine "Yella" Carraby and Andre "Dr. Dre" Young who were DJs on KDAY.
