That wise science called rumourology whispered this act was nothing but a grim offshot carried out by heavy metal merchants Virgin Steele. Anyway, feel free to believe it or not, but putting your ears on"Nightmare theatre" could be revealing, since the music here is thrash metal although showing plenty of heavy metal nuances that remind loosely several 80's heavy tunes. A closer analysis could invert that circumstance so we'd be talking about heavy metal played a la thrash! "Nightmare theatre" is an album that shows the two sides of the coin over and over, keeping its sound addicting and overly enjoyable. Vocals are violent and evil, low and eerie. Some people say Exorcist is one of the early death metal bandsand maybe can be seen as Possessed and Death underground forefathers. Leaving behind any speculation about pointless definitions, "Nightmare theatre" is a great and highly influential LP. 37 minutes of enjoyable and entertaining hellish heavy metal will please your soul and body with a Venom like approach over a strong proto-death structure that can be seen as a wild mix between Sodom, Mercyful Fate and early Slayer.
