Although some choose to pass off Jamiroquai as a Stevie Wonder-clone, the band has amassed a steady stream of hits in its native U.K. and has experienced chart success in just about every other area of the world with an irresistible blend of house rhythms and '70s-era soul/funk. The band has gone though several lineup changes during their career, but through it all their leader has remained singer/songwriter Jason Kay (aka J.K.).
