Houses of the Holy is the fifth studio album by the English rock band Led Zeppelin, released on 28 March 1973 in the United States and on 30 March 1973 in the United Kingdom by Atlantic Records. The album benefited from two band members installing studios at home, which allowed them to develop more sophisticated songs and arrangements and expand their musical style. Several songs subsequently became fixtures in the group's live set, including "The Song Remains the Same", "The Rain Song" and "No Quarter". Other material recorded at the sessions, including the title track, was shelved and released on the later albums Physical Graffiti (1975) and Coda (1982). All instruments and vocals were provided by the band members Robert Plant (vocals), Jimmy Page (guitar), John Paul Jones, and John Bonham (drums). The album was produced by Page and mixed by Eddie Kramer. The cover was the first for the band to be designed by Hipgnosis and was based on a photograph taken at Giant's Causeway in Northern Ireland.

Led Zeppelin were an English rock band formed in London in 1968. The group comprised vocalist Robert Plant, guitarist Jimmy Page, bassist and keyboardist John Paul Jones, and drummer John Bonham. With a heavy, guitar-driven sound, they are cited as one of the progenitors of hard rock and heavy metal, although their style drew from a variety of influences, including blues and folk music. Led Zeppelin have been credited as significantly impacting the nature of the music industry, particularly in the development of album-oriented rock (AOR) and stadium rock.
