Nice review, I agree the elephants were marching in full force last night. Backbone has to be one of the heaviest live songs I have ever heard.
From what I recall Devin Townsend played:
Planet of the Apes
There was an extended jam session before Toxic Garbage Island - they had some dude in shorts come up and play guitar and sing. They described him as "a real death metal growler" and he did indeed have some good growls. I am not sure who he was, anyone else who might have been there recognize him?
