Check out this swell article in STYLUS, about some of the artists who do album covers for metal bands. Artists featured include Larry Carroll (covers for Slayer's REIGN IN BLOOD and CHRIST ILLUSION) and Baroness guitarist / artist John Dyer Baizley, one of my favorite artists right now. (By a different designer, the Nasum GRIND FINALE cover featured in the article is one of my all-time favorite metal covers.)
