BLUE MAN GROUP, but lookout... recording has huge dynamic range, and this recording challenges the limits of components more than any other recording I've heard. I'm willing to bet that it would make even the big Krell's with big daddy speakers sound inadequate. If you've ever seen their performance in Chicago, you will know what I mean. They pound away on monstrous unamplified drums, and you think your eardrums are gonna blow out. Bought CD at Best Buy, so I'm sure it's available elsewhere. Anyone else try this recording?
