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 downtempoelectronic music that grew out of England's hip hop and house scenes.

Many of the artists labeled in the genre express distaste in the label, saying they would much rather be labeled as Hip Hop or not have a genre at all. Sometimes characterized by a reliance on breakbeats and a sample-heavy, often moody sound pioneered by Coldcut's remix of Eric B. & Rakim's "Paid in Full", trip hop gained notice via popular artists such as Massive Attack, Moloko, Portishead, Tricky, Björk, Thievery Corporation, Amon Tobin, and rock-influenced sound groups such as Ruby, California's DJ Shadow, Cut Chemist, Gorillaz, Unkle, and the UK's Howie B. Morcheeba, originating from Hythe in Kent, Londoners Glideascope and New York's Bowery Electric are also often associated with this sound. The latest additions to this line of performers are Jem, Australia's Spook and the Anglo-Polish experimental collaboration Flykkiller.
