Trip-hop originated in Bristol, UK in the late 1980s and early 1990s, combining elements of hip hop, electronic music, and R&B. Key artists who helped define the genre include Massive Attack, Portishead, and Tricky. Trip-hop tracks are typically downtempo, with atmospheric and sample-heavy compositions featuring soulful female vocals over bass-driven beats between 80-110 BPM. The genre emphasizes mood and texture over lyrics, with an overall psychedelic and melancholic tone.
