Led by Ian Anderson, Jethro Tull was the first group from the progressive era to score resounding chart success. Originally their music was based in rhythm and blues, but punctuated with Anderson's flute playing and larger-than-life stage persona. By Thick As A Brick, the band would provide the ultimate concept album: one song spread over both sides of the album, housed in a newspaper-facsimile record jacket. By the mid-70s, the bands work become more formulaic, but fan favorites were just around the corner, as the folk-roots of Songs For The Wood would attest.
