I assume that most of the people who read this blog would be somewhat familiar with Switzerland's Hellhammer. With all of the various stories it is arguable just how solely influential these guys were on metal, and I suspect that opinions on just who was the most pioneering of that original handful of bands would differ from person to person, but you can't deny that Tom Gabriele Fischer and co. definitely left their mark on modern heavy music. This is a recent reissue of their album "Apocalyptic Raids". A Back On Black repress on clear vinyl, Noise Records originally pressed this back in 1984.
Gatefold LP, though I doubt the original came in such a package.
