Wreckx-N-Effect earned a huge crossover smash with the single "Rump Shaker" off their 1992 album Hard or Smooth. The accompanying video with its array of shapely women following the directions of the lead singer generated nearly as much heat as Sir Mix-A-Lot's "Baby Got Back." It also helped the group secure a platinum certification, something it hardly seemed they'd earn from their Motown debut Wrecks-N-Effect in 1991. Markell Riley, brother of super-producer Teddy Riley, was part of the rap ensemble along with Aquil Davidson and Brandon Mitchell; Mitchell was killed in a 1990 shooting. Following the success of "Rump Shaker," the group resurfaced in 1996 with Rap's New Generation. ~ Ron Wynn, Rovi
