@Foreigner1: I think the bird is fine--maybe a little ringing in the ears, but no psychological damage. I grew up with 2 cockatoos and they love music, dancing, and acting a little crazy once in a while. My parents birds do this all the time, although they have different musical tastes.
If he was acting like this all the time, then you can get worried.
Call me a dork, but I see an animal that defintely is not okay here. If a cockatoo looks ruffled in his feathers like this and behaves like that, it has psychological problems. It does not feel well.
So the only thing I can say here is- Poor animal... So sad to see- my heart bleeds for this creature.

But really, I'm inclined to agree with Screen Sleuth. The sound of that must be killing his ears.
