Scion A/V released the five-song EP Teratogenesis by Revocation. And best of all, as long as you're willing to give up your email address, it's free to download. Just go here and get it, or give the stream a listen first and then download it.
Last year's full-length Chaos of Forms was very good. If you like that one, then you should dig the new EP. The guitar playing can get a little technical at times, but it's never in an over-the-top kind of way. If you like Teratogenesis, then definitely check out Chaos of Forms if you haven't done so already.
