K-Klass are a Welsh/English electronic music group from Wrexham, Wales and Chester, England, who are based in Manchester, England. Its original members were Andy Williams, Carl Thomas, Russ Morgan and Paul Roberts.

In 1991, K-Klass signed with the label Deconstruction Records, scoring five top-40 hits on the UK Singles Chart, and later signed to Parlophone. In the mid-1990s, K-Klass were one of the busiest and most successful remix acts around, remixing the likes of Bobby Brown, Janet Jackson and Luther Vandross, New Order, Rihanna, The Corrs, and Whitney Houston. They were awarded the IDA remixers of the year in 1996 for their mix of Carleen Anderson's "True Spirit", then received a Grammy nomination in 2002 for their remix of Samantha Mumba's "Baby Come on Over". Since leaving Parlophone, Williams and Thomas have both left K-Klass, leaving just Roberts and Morgan alongside original vocalist Bobbi Depasois as K-Klass. Roberts and Morgan run their own record label, Klass Action.^[1]
