Church of Anthrax is a collaborative studio album by musicians John Cale and Terry Riley. It was released in February 1971 by record label Columbia, nearly a year after the material was recorded; in fact, it was recorded prior to Cale's solo debut Vintage Violence.
Melody Maker described the album as, "An uneven record, remarkable for one excellent Cale song ("The Soul Of Patrick Lee") and the title track, a brilliantly dense piece of production. Cale's viola and bass and Riley's organ and saxophone create an impenetrable, organic vortex of sound. One of the all-time great headphones tracks, featuring the avant-garde at its funkiest."
