UK electronic music act formed by Rick Smith and Karl Hyde in 1987 after their former band Freur disbanded. The first line-up released more song oriented funky guitar based pop over the course of two albums. In 1991 the core duo returned with a new track oriented technoid direction and a new ally: DJ Darren Emerson. In 1996 the former b-side "Born Slippy NUXX" was used in Danny Boyle's film "Trainspotting" and became an instant anthem of the mid to late 1990's. Emerson left in 2000 after the release of "Everything, Everything" to pursue a solo career and was replaced on tour DJ duties by Darren Price. Price became a performing member of Underworld Live in 2005.
