'Thick As A Brick' was the fifth studio album by Jethro Tull, originally released in 1972.

The album is notable for only including one song, which spans the entire album. 'Thick As A Brick' was deliberately crafted in the style of a concept album (and as a "bombastic" and "over the top" parody). The original packaging, designed like a newspaper, claims the album to be a musical adaptation of an epic poem by a (fictional) 8-year-old genius, though the lyrics were actually written by the band's frontman, Ian Anderson.
