"Pump Up the Volume" is the only single by British recording act M|A|R|R|S. Recorded and released in 1987, it was a number-one hit in many countries and is regarded as a significant milestone in the development of British house music and music sampling. The song derives its title directly from a lyrical sample from "I Know You Got Soul", a hit single by labelmates Eric B. & Rakim, released months prior in that same year.

The single was the product of an uneasy collaboration between electronic group Colourbox and dream pop band A.R. Kane, two groups signed to the independent label 4AD. The A-side was written primarily by Colourbox, while the B-side "Anitina" was primarily an A.R. Kane creation. The link-up was suggested by label founder Ivo Watts-Russell after the two groups had independently suggested the possibility of releasing a commercial dance record, inspired by the American house music that was starting to make an impact on the UK chart.
