Psychedelic soul, sometimes called black rock, is a sub-genre of soul music, which mixes the characteristics of soul with psychedelic rock. It came to prominence in the late 1960s and continued into the 1970s, playing a major role in the development of funk music and disco.
Following the lead of Jimi Hendrix in psychedelic rock, in the late 1960s psychedelia began to have a widespread impact on African American musicians, particularly the stars of the Motown label. Influenced by the civil rights movement, it had a darker and more political edge than much acid rock. Building on the funk sound of James Brown, it was pioneered by Sly and the Family Stone with songs like "Dance to the Music" (1968), "Everyday People" (1968) and "I Want to Take You Higher" (1969), which had a sound that emphasized distorted electric rhythm guitar and strong basslines. Also important were the Temptations and their producer Norman Whitfield, who moved from a relatively light vocal group into much more serious material with "Cloud Nine" (1968), "Runaway Child, Running Wild" (1969) and "Psychedelic Shack" (1969).
Other Motown acts soon followed into psychedelic territory, including established performers like the Supremes with "Reflections" (1967), "Love Child" (1968), and "Stoned Love" (1970). Psychedelic influences could also be heard in the work of Stevie Wonder and in Marvin Gaye's socially conscious work from What's Going On (1971). Acts that broke through with psychedelic soul included The Chambers Brothers with "Time Has Come Today" (1966, but charting in 1968), The 5th Dimension with a cover of Laura Nyro's "Stoned Soul Picnic" (1968), Edwin Starr's "War" (1970) and the Undisputed Truth's "Smiling Faces Sometimes" (1971).
George Clinton's interdependent Funkadelic and Parliament ensembles and their various spin-offs, took the genre to its most extreme lengths, making funk almost a religion in the 1970s. Influenced by Detroit rock groups including MC5 and The Stooges, they used extended distorted guitar solos and psychedelic sound effects, coupled with surreal imagery and stage antics, especially on early albums such as Funkadelic (1970), Free Your Mind...And Your Ass Will Follow (1970), and Maggot Brain (1971), producing over forty singles, including three in the US top ten, and three platinum albums.
Decline and influence 
While psychedelic rock began to waver at the end of the 1960s, psychedelic soul continued into the 1970s, peaking in popularity in the early years of the decade, and only disappearing in the late 1970s as tastes began to change. Acts like Earth, Wind and Fire, Kool and the Gang and Ohio Players, who began as psychedelic soul artists, incorporated its sounds into funk music and eventually the disco which partly replaced it.
