In the mid-1990s, the dreamy-but-grooving sound of trip-hop was confined to the U.K. underground until Portishead brought it to the worldwide mainstream. Combining electronics, lush production, Ennio Morricone-like guitar breaks, and angelic singing from frontwoman Beth Gibbons, the band became a leader of the trip-hop movement. Portishead split after its second album, and Gibbons eventually went the solo route with her critically lauded 2002 album OUT OF SEASON.
