Blues Traveler is an American rock band known for its blues and folk-infused style, formed in 1987. The band's distinctive elements include the harmonica skills of lead vocalist John Popper and their improvisational live shows. Their breakthrough came in the mid-1990s with the hit singles "Run-Around" and "Hook", from the album "Four" which gained significant radio airplay. Blues Traveler's influence lies in their fusion of blues-rock with pop sensibilities, paving the way for similar bands in the late 90s and early 2000s.
