In a previous rock covers band we did 'Cochise' and it was a highlight of the set. Spine-chilling line to play, IF the rest of the band are up to it which in this case they were. I miss that band, but not the bum-shattering volume we played at.
What a great description! I've played loud, but never to the point of shattering my bum. Not that I was aware of, anyway. I was also in a band some years ago that had Cochise in their set. Girl singer, and she could do it, too.
