Of course, a lot of rock is the spectacle. I listened to the flute playing on the link, sure, but I took with a grain of salt the goofy hair, the sweat, the anguished inhalations.

Pure theater - here is a MAN, and he's suffering!

Wikipedia says that in 1992 his daughter started studying flute, and she told him he was fingering wrong. He listened to her and changed his ways. Maybe she got him to play in an ergonomic fashion, and that helped alleviate the suffering. I dunno.

By the way, my MIDI program can simulate the sound of a flutist inhaling. It used to be considered a fault, but now I guess it's cool.
