This Pittsburgh male/female dance duo had a huge international smash in 1990 with "The Power." London-based rapper Turbo B. and his cousin Jackie Harris teamed on "The Power," with Harris' curdling vocal elevating Turbo B.'s pedestrian rap. But by the time things got rolling, Harris was already gone, replaced by Penny Ford, a former Gap Band background vocalist. Turbo B. himself departed in 1992, shortly after their second Arista LP, The Madman's Return, hit the streets. He was replaced by Nikki Harris, a former Madonna background vocalist. Snap! had a second big hit in 1990 with the number five pop single "Rhythm Is a Dancer." ~ Ron Wynn, All Music Guide
