WULCAN - Mysterier 7'' (1982) Sweden
Another new discovery and possibly the best 'unknown super-rarity' I've come across so far.
"Mysterier" ("Mysteries") is a deadringer for BLACK SABBATH's "Heaven and Hell" and therefore it is also a superb, ultra-heavy epic whose lack of originality feels totally irrelevant.
The fact that B-side "Travellin'" sounds like warmed over STATUS QUO matters little when you can play the A-side over and over again while oogling the ultra-cult cover art without ever getting tired of that pounding lead riff.
Let's pretend that 2nd aor 7" from '86 never happened.
