Acid jazz is a music genre that combines elements of funk, soul, and hip hop, as well as jazz and disco. Acid jazz originated in clubs in London during the 1980s with the rare groove movement and spread to the United States, Western Europe, Latin America and Japan. Acts included The Brand New Heavies, Incognito, James Taylor Quartet, Us3, and Jamiroquai from the UK, and Guru, Buckshot LeFonque and Digable Planets from the U.S. The rise of electronic club music in the middle to late 1990s led to a decline in interest, and in the twenty-first century, acid jazz became indistinct as a genre. Many acts that might have been defined as acid jazz are seen as jazz-funk, or nu jazz.
