The Pretty Things were a 60's British rock band that evolved from simple rhythm and blues to psychedelic music and concept albums. Originally sounding like a rawer version of the early Rolling Stones sound, the Pretty Things would make their biggest statement in history with the concept album S.F. Sorrow Is Born and the strong set of tunes on Parachute. S.F. Sorrow apparently made quite an impression on Pete Townsend, as inspiration for what would turn out to be Tommy.
