Procol Harum

Procol Harum is a British rock band, formed in the 1960s, who built an important foundation for what would become progressive rock, or perhaps more closely, symphonic rock. They are best known for their 1967 hit single "A Whiter Shade of Pale", which is not only a regular item on classic singles polls, but is also regarded as being a seminal track in the development of pop music and particularly progressive rock music. Procol Harum have had a devoted following throughout their career; their music, although being principally noted for its classical influence, also embraces the blues and pure pop music.
