Grebo (or grebo rock) was a short-lived subgenre of alternative rock that incorporated influences from punk rock, electronic dance music, hip hop and psychedelia. The scene occupied the period in the late 1980s and early 1990s in the United Kingdom before the popularisation of Britpop and grunge.
The word "grebo" was originally used as a slang term for bikers and rock music fans with long hair. The word was re-fashioned by the group Pop Will Eat Itself that represented a brand of United Kingdom subculture of the late 1980s and early 1990s, largely based in the English Midlands. The scene particularly centred in Birmingham.
Influential bands in the scene were Pop Will Eat Itself (who had songs titled, "Oh Grebo I Think I Love You" and "Grebo Guru"), The Wonder Stuff, Ned's Atomic Dustbin, along with London band Carter USM and Leicester bands Crazyhead, The Bomb Party, The Hunters Club, Scum Pups and Gaye Bykers on Acid. The term has also been used to describe Jesus Jones, who enjoyed success in both the United Kingdom and the United States.
The movement, although short-lived, was a success at the time, and influenced a number of later bands. To a certain extent it was a music press invention, much like "positive punk", a scene and style named by British indie magazines, specifically NME and the Melody Maker.
Grebo bands drew influences from a diverse array of genres, including dance-rock, psychedelia,pop, hip hop,punk rock and electronica. Pop Will Eat Itself adopted an industrial alternative rock style that combined "heavy metal and hard rock guitar riffs, electro-dance rhythms, samples and rap vocals." While Gaye Bykers on Acid's use of hip-hop and dance beats was considered as "a major innovation in mid-'80s alternative rock," Ned's Atomic Dustbin focused on "the hyper punk aspect" of the movement, relying on "catchy hooks and a dual-bass sound."
