Garage rock is a raw and energetic style of rock and roll that flourished in the mid-1960s, most notably in the United States and Canada 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 Nuggets did much to define and memorialize the style. The term derives from the perception that groups were often made up of young amateurs who rehearsed in the family garage, though many were professional. The phrase garage band is often used to refer to musical acts in this genre.
