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, and has experienced a series of subsequent revivals. The style is characterized by basic chord structures played on electric guitars and other instruments, sometimes distorted through a fuzzbox, as well as often unsophisticated and occasionally aggressive lyrics and delivery. Its name derives from the perception that groups were often made up of young amateurs who rehearsed in the family garage, although many were professional.

Beat music, British beat, or Merseybeat is a British popular music genre that developed, particularly in and around Liverpool, in the late 1950s and early 1960s. The genre melded influences from British and American rock and roll, rhythm and blues, skiffle, traditional pop and music hall. It rose to mainstream popularity in the UK and Europe by 1963 before spreading to North America in 1964 with the British Invasion. The beat style had a significant impact on popular music and youth culture, from 1960s movements such as garage rock, folk rock and psychedelic music.
