Russian composer Alfred Schnittke wrote his Symphony No. 2, subtitled "St. Florian" and "Invisible Mass" in 1979. It is a choral symphony, written for contralto, countertenor, tenor and bass, plus chorus and orchestra. The symphony was written in homage to 19th century Austrian composer and organist Anton Bruckner, who was closely associated with St. Florian's Priory in the town of Sankt Florian, Upper Austria, and who is buried under the organ there.
