Oh no, that's the worst news I've heard since Corey Smoot's death! It's hard to sing like he does in perfect health, so I can only imagine what that condition must do to him.
Lucky! He seems like a really laid back guy from the interviews I've seen of him, plus his story videos. What mag do you write for? I got to talk to some of the guys from Death Angel after a show. Their guitarists are awesome to chat with! Wish I got the meet-and-greet with Soilwork.
