Jethro Tull’s Thick as a Brick album consists of 2 songs, and it’s as much a work a poetry as music. The meandering composition of avant garde instrumentation carry you along while the lyrics explore an audaciously broad set of overlapping themes. It’s truly epic achievement through and through, including the album cover that unfolded into a tabloid newspaper brimming with absurdity–and this was decades before The Onion.
