Underworld is a British electronic music group formed in the early 1980s by Karl Hyde and Rick Smith. Initially, the band explored synthpop sounds, but it was in the 1990s that they gained critical acclaim and commercial success. Their breakthrough came with the release of the album 'Dubnobasswithmyheadman' in 1994, which showcased their innovative blend of techno, trance, and house music. Underworld is best known for their iconic track 'Born Slippy .NUXX,' which became an anthem of the 90s rave scene, especially after its inclusion in the film 'Trainspotting.' Over the years, they have remained influential in the electronic music scene, consistently releasing new material and maintaining a vibrant live presence.
