Portishead released the 1994 alternative album Dummy, which features the song "Glory Box." The record helped establish the Bristol sound associated with trip hop, a style blending hip-hop rhythms, electronic production, and atmospheric vocals.
The band consisted of Geoff Barrow, Beth Gibbons, and Adrian Utley. Barrow had worked at Bristol's Coach House Studios, where he developed production techniques that combined sampled drums with cinematic textures and vintage-sounding instrumentation.
Dummy won the 1995 Mercury Music Prize and became one of the defining albums of 1990s alternative music. "Sour Times," "Numb," and "Roads" are among its other notable tracks. Massive Attack and Tricky are related Bristol artists, but neither made Dummy.
