One of the more omnipresent remixing teams on the British house scene of the 1990s, K-Klass emerged in the late '80s, founded by Andy Williams and Carl Thomas after the demise of their previous band, Interstate (who had played with 808 State on the early house scene). The Welsh duo added Paul Roberts and Russ Morgan, and began recording with 1990's Wildlife EP. Late the following year, K-Klass' single "Rhythm Is a Mystery" reached the Top Five and they began their continual residence in the club charts with later singles "Don't Stop," "Let Me Show You," and "What You're Missing," from their debut album, 1993's Universal.

By the mid-'90s, K-Klass had begun to move away from the original blueprint of British house and toward a more mainstream, song-oriented approach -- though one that embraced trance, nu-disco, and even ambient-house. K-Klass remixes of Whitney Houston, Blondie, Frankie Knuckles, M People, Lulu, Bizarre Inc., and Bobby Brown became sizable dancefloor hits. The 1996 K-Klass LP Remix and Additional Production displayed their allegiance to post-production, while their 1998 effort K2 featured new tracks with Rachel McFarlane and Diane Charlemagne among the album's guest vocalists. They received a 2002 Grammy nomination in the Best Remix category for their work on Samantha Mumba's track "Baby Come on Over." In 2012 they formed the label Klass Action and released their "Rock the House" single on the imprint. ~ John Bush, Rovi
