Liquid Soul is an American jazz, hip-hop, funk, freestyle fusion ensemble, formed in 1993 from Chicago, Illinois, which helped pioneer the acid jazz movement in the United States in the 1990s. Coined "Beyond Acid Jazz" by founder Mars Williams who played with The Psychedelic Furs and previously with The Waitresses and Billy Idol, the group was co-founded by guitarist Tommy Klein, from the Spies Who Surf, and Chicago DJ Jesse De La Peña. The band's 2000 album Here's the Deal was nominated for a Grammy in the Best Contemporary Jazz Album category.
