Uriah Heep are an English rock band, formed in December 1969 when record producer Gerry Bron invited keyboardist Ken Hensley (previously a member of The Gods and Toe Fat) to join Spice, a band signed to his own Bronze Records label. Sometimes jokingly referred to as "The Beach Boys of heavy metal" for their melodic songs, and trademark multi-part harmony backing vocals, although their music draws on diverse influences including: progressive rock, hard rock, heavy metal, jazz and even country on occasion. As one of the first bands to fuse progressive with metal, they are a precursor to the progressive metal genre.   Wikipedia
