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.
