Trip hop (sometimes used synonymously with "downtempo") is a musical genre that originated in the early 1990s in the United Kingdom, especially Bristol. It has been described as "a fusion of hip hop and electronica until neither genre is recognizable", and may incorporate a variety of styles, including funk, dub, soul, psychedelia, R&B, and house, as well as other forms of electronic music. Trip hop can be highly experimental.
Deriving from later idioms of acid house, the term was first used by the British music media to describe the more experimental variant of breakbeat emerging from the Bristol Sound scene in the early 1990s, which contained influences of soul, funk, and jazz. It was pioneered by acts like Massive Attack, Tricky, and Portishead. Trip hop achieved commercial success in the 1990s, and has been described as "Europe's alternative choice in the second half of the '90s."
