Acid jazz, also known as club jazz, is a musical genre that combines elements of jazz, soul, funk and disco. Acid jazz originated in the London club scene of the mid-1980s in the rare groove movement and spread to the US, Japan, Eastern Europe and Brazil. Major acts included Brand New Heavies, Incognito, Us3 and Jamiroquai from the UK and Buckshot LeFonque and Digable Planets from the US. The rise of electronic club music in the mid to late 1990s led to a decline in interest, and in the twenty-first century, the movement became indistinct as a genre. Many acts that might have been defined as acid jazz are now seen as jazz-funk, neo soul or jazz rap.
