Procol’s Ninth (1975)
The Well’s on Fire (2003)
Procol Harum () is an English rock band formed in 1967. It contributed to the development of symphonic rock, and by extension, progressive rock. Its best-known recording is their 1967 hit single "A Whiter Shade of Pale", considered a classic in popular music and one of the few singles to have sold over 10 million copies. Although noted for its baroque and classical influence, Procol Harum’s music also embraces the blues, R&B, and soul.
