Garage rock is a raw form of rock and roll that was first popular in the United States and Canada from about 1963 to 1967. During the 1960s, it was not recognized as a separate music genre and had no specific name. In the late 1970s, some rock critics retroactively identified it as an early incarnation of punk rock, and it is sometimes called garage punk, protopunk, or 1960s punk; however, the music style has predominantly been referred to as garage rock.
