is a style of pop music
, a raw and energetic variety of rock and roll
that flourished in the mid-1960s most notably in the United States
, but also elsewhere. At the time it had no specific name and was not recognized as a separate genre
, but critical recognition in the early 1970s, and particularly the release of the 1972 compilation album
, , did much to define and memorialize the style. The term derives from the perception that many groups were young amateurs who rehearsed in the family garage, though many were professional.
