The pioneering force behind the rise of trip-hop, Massive Attack were among the most innovative and influential groups of their generation; their hypnotic sound -- a darkly sensual and cinematic fusion of hip-hop rhythms, soulful melodies, dub grooves, and choice samples -- set the pace for much of the dance music to emerge throughout the 1990s, paving the way for such acclaimed artists as Portishead, Sneaker Pimps, Morcheeba, UNKLE and Tricky, himself a Massive Attack alumnus.
