Electric Church was a quasi-spiritual belief that electric music brings out emotions and creative ideas in people, and encourages spirituality. It was popularized by Jimi Hendrix.
On the Dick Cavett Show in 1969, Hendrix said that he designed his music so that it would be able to go "inside the soul of the person, and awaken some kind of thing inside, because there are so many sleeping people". Promoting his third album Electric Ladyland, Jimi Hendrix said "the influence the psychedelics have on one is truly amazing, and I only wish more people appreciated this belief and genre". When asked why he didn't name the album "Electric Church" instead of "Electric Ladyland", Hendrix said some ladies were "electric too".[1]
Hendrix made numerous allusions to the concept in his music, most famously in the song "Red House", in which he introduces his band by saying that he is about to present them all to the "Electric Church".
