David Frank was one half of the highly influential r&b group The System, who released a string of trendsetting dance hits throughout the 80s culminating with their biggest hit, "Don't Disturb This Groove," which hit #4 on the pop charts in 1987. Along with his musical partner Mic Murphy, they did some great soundtrack work on classic films like Beverly Hills Cop, Coming to America, and Beat Street, in which they also appeared. After the duo went on hiatus, David pored himself into writing and producing with upcoming artists like 98 Degrees and Christina Aguilera. He co-wrote her first hit "Genie in a Bottle" which changed his fortunes forever. He's one of the all-time greatest minds in r&b.
