Don't they typically have their "Ballet" show with some extreme music on the PA... as opposed to actually showing up to the bands actual live show and doing a performance? (God, I hope that made sense..) Is this the first time they have actually done that? I wonder of the dancers are nervous about what kind of reception they will get...
Kudos for the guys being so cool to let this happen... and I hope our fellow Opethians are respectful and don't laugh or boo.... I would expect the Ålmighty to smite their asses if necessary, but I'm sure the fans will act appropriately. Especially since we are so much smarter, cultured and diverse, right?
