Stephen Kasner is another artist with a name that may not be familiar, but whose work speaks for itself.  He did the artwork for Khlyst’s "Chaos is My Name", and has also done work for Himsa, Sunn O))), and numerous other bands.  Kasner’s style is quite dark, often bringing to mind the distorted and damaged figures of Francis Bacon’s paintings. 

Stephen Kasner’s website has a great gallery of his work, and you can also buy originals, prints, silkscreens, and posters of his works.  Kasner has recently released Stephen Kasner: Works 1993-2006, which is available at Amazon and Aquarius Records.
