Armageddon were an English hard rock band formed in 1974. Their self-titled debut, Armageddon, was recorded in England and released in the United States on A&M Records. The albums' original liner notes use the term "supergroup", as their personnel were drummer Bobby Caldwell (previously a member of Captain Beyond), singer Keith Relf (who had fronted the band Yardbirds and was a co-founder of Renaissance), guitarist Martin Pugh (from Steamhammer), and bassist Louis Cennamo (also formerly of Renaissance and Steamhammer).
