Freakbeat is a loosely defined subgenre of rock music that emerged in the mid-1960s, primarily in the UK. It evolved as a progression from Merseybeat and British Invasion pop, coexisting alongside R&B. Freakbeat is characterized by raw, energetic performances, distorted guitar riffs, and driving rhythms. Often seen as a precursor to psychedelic rock, proto-punk and power pop, it embodied a rebellious spirit and experimental edge.
