Now that you mention it, I'm not entirely sure. I've cropped the logo and thrown it in a few reverse image searches, all the results imply Xavleg in one way or another, google led me to a post on (presumably) the band's facebook page titled "XavlegbmaofffassssitimiwoamndutroabcwapwaeiippohfffX Design Comp", but I can't see it because it's private. Assuming that's real, maybe it's an old/WIP logo of theirs.
