I wanted to share with you this very underground/unknown yet absolutely amazing artist. His name is John Baizley. He hasn't done much work and he doesn't really have much advertisement. I found out about him because he did all of the amazing album covers for the post-metal band Baroness (who I saw open for Opeth last time, I'd recommend them for fans of Mastodon, Isis, Cult of Luna, etc). He's from Savannah Georgia (same place as Baroness) and he works with appears to be inks and watercolors.
