In the early 1990s, Dutch DJs developed a style of electronic dance music called gabber. The style was developed in reaction to the commercialization of house music and was heavily influenced by early hardcore from Frankfurt and New York City. The DJs stripped the music of what they perceived as excess sounds, songs were reduced to a high-speed monotonous beat, of sometimes over 260 beats per minute. The first ever record to be labeled gabber was 'Amsterdam waar lech dat dan?' by Rotterdam-based 'The Euromasters' as a reaction to the media always focusing on Amsterdam. It has to be said that Amsterdam-based D-Shake was probably to be the first to use the term gabber in a 1990 Dutch TV program. Important gabber groups and DJs are the Rotterdam Terror Corps, The Dark Raver and Neophyte. Gabbers distinguish themselves through hair (bald heads) and clothes (Australian and Cavello). Now, gabber is usually called early hardcore. Gabber also spawned happy hardcore, an offshoot of gabber and Breakbeat Hardcore, a genre of dance music that originated in England. Important groups and DJs in happy hardcore include Charly Lownoise and Mental Theo, Party Animals and Flamman & Abraxas.
