Who? A love of hip-hop brought Chromeo members Dave One and Pee Thug together in high school, but an infatuation with '80s black pop music -- think Prince, Cameo and The Jets -- soon took over. Pee Thug's army of analog keyboards, moogs and drum machines provided the musical artillery for early singles such as "Destination Overdrive" that piled on bouncy, frivolous fun.

Who? After six years as one of a trio of lead singers/guitarists for revved-up southern rockers Drive-By Truckers, Jason Isbell bid farewell to the band in April 2006.
