Elementfour was a music producing duo made up of DJ Paul Oakenfold and musician/composer Andy Gray. Sometime before July 2000, they collaborated in writing and producing the opening theme for the Channel 4 reality series Big Brother. The theme, which was later released as a single, continued to be used when Big Brother and Celebrity Big Brother moved to Channel 5 from 18 August 2011 until the show was axed and ended on 5 November 2018. A sample from the track was used again in 2022 to promote the upcoming 2023 series on ITV2. From Wikipedia →
