Thick as a Brick is the fifth studio album by the British rock band Jethro Tull, released on 3 March 1972. The album contains a continuous piece of music, split over two sides of an LP record, and is intended as a parody of the concept album genre. The original packaging, designed as a 12-page newspaper, claims the album to be a musical adaptation of an epic poem by fictional eight-year-old genius Gerald Bostock, though the lyrics were actually written by the band's frontman, Ian Anderson.
