Legacy of Rick Wakeman

Sabbath Bloody Sabbath is the fifth studio album by the English heavy metal band Black Sabbath, released on 30 November 1973. It was produced by the band and recorded at Morgan Studios in London in September 1973. The writing process for the album, which began in Los Angeles, California, was initially hampered in part by the band's substance abuse and fatigue following its 1972–1973 world tour in support of their previous album, Vol. 4. In an effort to get past their writers' block, the band relocated to Clearwell Castle in the Forest of Dean, Gloucestershire, England, where guitarist Tony Iommi conceived the main riff of what became the album's title track and lead single.

U.K. were a British progressive rock supergroup originally active from 1977 to 1980. The band was founded by bass guitarist John Wetton and drummer Bill Bruford, formerly the rhythm section of King Crimson. The band was rounded out by violinist/keyboardist Eddie Jobson, and guitarist Allan Holdsworth. Bruford and Holdsworth left in 1978, and Bruford was replaced by drummer Terry Bozzio. Jobson, Wetton and Bozzio reformed U.K. for a world tour in 2012.
