rock band

Rock band (or rock group) is a generic name to describe a group of musicians specializing in a particular form of electronically amplified music. Deriving its name from the musical style which was its immediate progenitor, rock and roll, the type of music played by rock groups has its roots deeply steeped in both rock and roll, and its immediate forebear, rhythm and blues.
