PENTAGRAM/MEZARKABUL - PENTAGRAM (1990)
No, not Pentagram from Virginia. Or Pentagram from Chile. Or Pentagram from Mexico. Or Pentagram from Sweden. THIS pentagram hails from Turkey (where they are known as Mezarkabul), and have been around for almost 20 years. Their newer stuff is more Power Metal-oriented, but this, their quasi-self-titled debut, is a straight-up thrasher, a shreddin' blast from the past that any fan of good Metal will dig.
PENTAGRAM - TURN TO STONE (2002)
Yes, THAT Pentagram. "Turn To Stone" is a compilation of 3 LP's released over the course of the last 2 decades. I hope you all have everything they've ever done already, but if not, this one is the place to start.
