I ... probably have an overly broad definition of neopagan. However, the wolf motif, combined with the implied veneration of blood, implied a certain veneration of nature and the primal to me. I might be incorrect in leaping from there to a whole category of belief systems. (This may not be relevant, since I didn't know it at the time of my initial reaction, but the profile and the most recent journal post have additional hints: interest in Celtic music (weak, I know), answer to "How did you come up with the name".)

Oh, and I'll grant you "weird" in a second. I'd point out, though, that it wasn't a spur-of-the-moment thing – in a comment, the artist mentioned having been waiting for the opportunity for a while. Which changes things some, although it makes it no more mainstream.
