Thick as a Brick is the fifth studio album by the British rock band Jethro Tull, released on 3 March 1972 on Chrysalis Records. The album consists of a single continuous piece of music, split across the two sides of the original LP record, and was conceived as a parody of concept albums and the progressive rock genre. Its original packaging took the form of a 12-page newspaper, which presented the album as a musical adaptation of an epic poem by a fictional eight-year-old prodigy named Gerald Bostock, although the lyrics were actually written by the band's frontman Ian Anderson. No. 1 on the Billboard 200 for 2 weeks, from the issue of June 3, 1972. Wiki link
