Wreckx-n-Effect was a New Jack Swing Hip-Hop group who had the multi-platinum hit "Rump Shaker" in 1992/1993, which was produced by Teddy Riley. The group, originally comprised of then adolescent; Aqil Davidson, Brandon Mitchell, Markell Riley, and Keith "K.C." Hanns, was formed around 1988 as Wrecks-n-Effect. Their first release, an eponymous EP of six tracks for Atlantic Records, included the singles "Go For What You Know", "Let's Do It Again" (which sampled The Staple Singers hit song), and a self-titled track sampling Jimmy Castor's "Bertha Butt Boogie".
