Jamiroquai are a British jazz funk and acid jazz band formed in 1992. Fronted by lead singer Jay Kay, Jamiroquai were initially the most prominent component in the early-1990s London-based acid jazz movement, alongside groups such as Incognito, the James Taylor Quartet, and the Brand New Heavies. Other Acid Jazz artists such as 'Moses Mayes' and Groove Collective are popular comparisons. Subsequent albums have explored other musical directions such as pop, rock and electronica. Their best known track is "Virtual Insanity", which won four awards at the 1997 MTV Video Music Awards. Jamiroquai have sold more than 35 million albums worldwide and won a Grammy Award in 1998. The band name is a portmanteau of "jam session" and "iroquai", based on the Iroquois, a Native American tribe. The original band was Jay Kay (vocals), Toby Smith (keyboard), Stuart Zender (bass), Nick Van Gelder (drums) and Wallis Buchanan (didgeridoo). These are the founding members of Jamiroquai and were involved in the writing and production of the first album. The lineup of the band has changed several times, and the longest serving and now core members of the band are lead singer and songwriter Jason "Jay" Kay and drummer Derrick McKenzie (since 1994). Kay was the impetus behind the formation of Jamiroquai, deciding to form the band after an unsuccessful audition to become the singer of the Brand New Heavies. Despite his self-professed attempts to treat Jamiroquai as a band, Kay has always been at the forefront of the band.
