I'm delusional and seem to believe that cryptopsy is the best band ever especially when it comes to speed. Jon Levasseur. Of course he might not be fast but he's got some good sweeping. Now their drummer on the other hand. He might be one of the fastest drummers out there. Not sure as I don't really look into drummers that much. But this is a guitar site not percussion site. To hell with drummers (don't take that serious)
