"Release the Pressure" is the third single released under the Leftfield name and the first to involve Paul Daley with writing duties after he joined the group. The song was released only on 12" in 1992. Unlike previous releases that had been released on the Outer Rhythm record label, Leftfield had now officially split from the Outer Rhythm record label. Major labels had offered them deals yet both members didn't want to give up creative control to any major company. They formed the Hard Hands record label with "Release the Pressure" being the label's first official release. The song featured reggae singer Earl Sixteen on vocals. It made the top 20 in the UK charts and featured at number one in the Melody Maker "Stone Free Chart of the Year". It was used in Telefónica O2 and O2 (UK) commercials during 2000's.
In 1996, an updated version of "Release the Pressure" was released as the eighth single under the Leftfield name. It was released on 12", CD and Cassette on 8 January 1996. It featured Earl Sixteen and Cheshire Cat on vocals with ad libs by Papa Dee. The song reached #13 in the UK charts. There were also four different remixes of the song with different ones as B-sides to the different format releases.
