Trip hop is a music genre also known as the Bristol sound or Bristol acid rap. The trip hop description was applied to the musical trend in the mid-1990s of downtempo electronic music that grew out of England's hip hop and house scenes. It is often rejected as a term by those artists to whom it is applied. It has also been described as "Europe's alternative of choice in the second half of the '90s", and a fusion "of Hip-Hop and Electronica until neither genre is recognizable." It is thus categorized as a fairly experimental genre, and sometimes with elements of Dance.
