What is "elementfour"

Elementfour (variants Element Four and Element 4) was a music producing duo made up of Paul Oakenfold and Andy Gray. They collaborated in writing and producing the tune as a theme song for Big Brother. The single entitled "Big Brother UK TV Theme" became a hit in August and September 2000 reaching #4 on the UK British Singles Chart. The original name for the track, as evidenced by promotional copies, was "Tast-E", and this was before the duo had settled on a collective name for themselves either.
