The critical and commercial triumphs have established Bristol as a centre of slow-burning creativity, but it was the staggering impact Massive Attack made with their debut album which first put the West Country town on the musical map and made reluctant superstars of Mushroom, 3-D and Daddy G. Blue Lines provided a blueprint for the sound which would become known as trip-hop, combining the raw soundsystem vibe of the Wild Bunch parties with immaculate production and the distinguished vocal talents of Tricky, and . From the understated beats and deftly-arranged ensemble rapping of the title track to the smokey paranoia of "Five Man Army" and the unrepeatable melancholic splendour of "Unfinished Sympathy", the album is a modern classic through and through. It won the Mercury Music Prize in 1992 and remains the finest work of a frighteningly talented group. --Ed Potton
