Steven Patrick Morrissey

Rammstein

For me it's got to be Disturbed (unless the blue man group counts)

I saw Wavves recently who put on a really bloody good show. Uhm... When I saw System of a Down a few years back I remember it being amazing actually. Queens of the Stone Age always blow me away too.

Bob Dylan... and Ween

I have to say 3, because they all have been amazing...
Deep Purple
Rush
TOTO

That I've seen this year? Spoon, I think, which I did not see coming, but they were way sexier live than I expected
