He recommends it!
(Note: I agree with Carson about Zirakzigil. They are fun.)
UPDATE: As Carson has indicated in the comments, his name on the bill is leftover and he is not performing at this show; the Know has confirmed this and WW has updated their listing as well. Meanwhile, Zirakzigil play fun instrumental Tolkien metal and their new tape is super cool and it comes in a case that looks like an old NES game and if you went to this show you would have a good time. The end.
