Armageddon was formed in 1974, and their self-titled debut, Armageddon, released in 1975, 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 the Yardbirds and was a co-founder of Renaissance), guitarist Martin Pugh (from Steamhammer), and bassist Louis Cennamo (also formerly of Renaissance and Steamhammer).

This classic has now been remastered and repackaged in a beautiful gatefold on 180G Atomic Red Vinyl to celebrate the 50th Anniversary. There is a Limited (100 copies) signed bundle that comes with a 10x10 print signed by all three surviving member (Bobby Caldwell, Louis Cennamo, Martin Pugh).
