The World Class Wreckin' Cru was an American electro hop group, consisting of DJ Yella, Dr.Dre and Cli-N-Tel.

They recorded some solid West Coast electro with Dr.Dre in the production chair, hitting the pop charts with a smooth love jam named "Turn Off the Lights" during 1988 (1988 in music), the same year Dre's N.W.A. delivered the gangsta landmark Straight Outta Compton. The group was formed by Lonzo (Alonzo Williams), owner of the Compton club Eve After Dark, who recruited a pair of popular local DJs, Dr.Dre and DJ Yella, along with Dre's high-school friend Cli-N-Tel. Early singles like "Surgery" and "Juice" -- many of them recorded at a four-track studio that was part of the Eve After Dark complex -- stood alongside work by the Egyptian Lover and L.A. Dream Team as stellar examples of the fast-moving fusion of old school rap and electro. But even as The World Class Wreckin' Cru became one of southern California's most popular rap acts, Dr.Dre and DJ Yella were pursuing other production opportunities, one of which came from a new label (Ruthless) formed by Eazy E. Along with Ice Cube, they wrote a single named "Boyz N The Hood" that was initially offered to the Ruthless act HBO, but later prompted the entire crew to form as N.W.A.. After street-level singles like "Dopeman" and "8 Ball" became huge local hits, The World Class Wreckin' Cru became less of a priority for both Dr.Dre and Yella. Even after the loverman ballad "Turn Off the Lights" entered the R&B Top 40 in 1988, they continued with N.W.A. and the group dissolved. Phases in Life, a World Class Wreckin' Cru LP released in 1990, was basically a solo release by Lonzo.
