Dave Matthews Band emerged from the jam-band underground of the 1990s to become an enduring American musical institution. Steeped in the progressive, multi-cultural sounds of the 1980s -- the group spliced bar band college rock with the jazz and worldbeat explorations of Paul Simon and Sting -- Dave Matthews Band built a following through word-of-mouth cultivated by traded cassettes of live performances, a trick learned from the Grateful Dead.
