Psychedelic funk (or funkadelia) is a music genre that combines funk music with elements of psychedelic rock. It was pioneered in the late 1960s by acts like Sly and the Family Stone and the Parliament-Funkadelic collective. It would influence later styles including '70s jazz fusion and the '90s West Coast hip hop style G-funk.
Following the late 1960s work of Jimi Hendrix, the music and drug culture of psychedelia began to have a widespread impact on African American musicians. Black funk artists such as Sly and the Family Stone borrowed techniques from psychedelic rock music, including wah pedals, fuzz boxes, echo chambers, and vocal distorters, as well as elements of blues rock and jazz. Producer Norman Whitfield would draw on this sound on popular Motown recordings such as The Temptations' "Cloud Nine" and Marvin Gaye's "I Heard It Through the Grapevine."
In the following years, groups such as Parliament-Funkadelic continued this sensibility, employing synthesizers and acid rock-oriented guitar work into open-ended funk jams. Led by George Clinton, P-Funk would shift the genre away from song-form and toward groove and texture. According to theorist Kodwo Eshun, Clinton's work would focus more on the abject elements of psychedelia in contrast to earlier artists, and by the mid-1970s explored themes related to space and Afrofuturism. In the early 1970s, jazz artists such as Miles Davis and Herbie Hancock combined elements of psychedelic funk with urban jazz to pioneer jazz fusion.
Subsequent artists would be influenced by the style including Prince.New wave band Talking Heads explored psychedelic funk, influenced by George Clinton, on a trilogy of acclaimed albums in the late 1970s. In the 1990s, a popular psychedelic funk style known as G-funk emerged from the West Coast hip hop scene, represented by Warren G, Dr. Dre, and Snoop Dogg. The 1990s hip hop duo OutKast were also influenced by black psychedelic musicians such as Sly Stone and Clinton.
