The British rock band Jethro Tull released Thick as a Brick, a parody concept album allegedly adapted from an eight-year-old boy's epic poem.

Jethro Tull are a British rock band formed in Blackpool, Lancashire in 1967. Initially playing blues rock and jazz fusion, the band soon incorporated elements of English folk music, hard rock and classical music, forging a signature progressive rock sound. The group's founder, bandleader, principal composer, lead vocalist, and only constant member is Ian Anderson, a multi-instrumentalist who mainly plays flute and acoustic guitar. The group has featured a succession of musicians throughout the decades, including significant contributors such as guitarists Mick Abrahams and Martin Barre ; bassists Glenn Cornick, Jeffrey Hammond, John Glascock, Dave Pegg, Jonathan Noyce, and David Goodier; drummers Clive Bunker, Barrie "Barriemore" Barlow and Doane Perry; and keyboardists John Evan, Dee Palmer, Eddie Jobson, Peter-John Vettese, Andrew Giddings, and John O'Hara.

Thick as a Brick is the fifth studio album by the British rock band Jethro Tull, released on 3 March 1972. The album contains one 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.

A concept album is an album whose tracks hold a larger purpose or meaning collectively than they do individually. This is typically achieved through a single central narrative or theme, which can be instrumental, compositional, or lyrical. Sometimes the term is applied to albums considered to be of "uniform excellence" rather than an LP with an explicit musical or lyrical motif. Music critics remain divided on the precise definition of a concept album.

In poetry, an epic is a lengthy narrative poem typically about the extraordinary deeds of extraordinary characters who, in dealings with gods or other superhuman forces, gave shape to the mortal universe for their descendants. With regard to oral tradition, epic poems consist of formal speech and are usually learnt word for word, and are contrasted with narratives that consist of everyday speech where the performer has the license to recontextualize the story to a particular audience, often to a younger generation.
