Hmm, most fun concerts were probably The Police Picnic, 1983, mostly for the dude behind us snorting chemical THC and barfing a lot...he was funny....good show as well, with Peter Tosh and James Brown, who were awesome. Also fun, Destroyer, a Kiss cover band I saw in Montreal who were hilarious. Left the makeup on after the show and sat around the bar trying to pick up chicks.
Saw Tori Amos at a tiny club on the Little Earthquakes tour, fantastic....sat so close I could almost touch her, was it not for the restraining order
For pure sonic value, the Kodo Drummers, and Godspeed You Black Emperor.
David Bowie....twice, Serious Moonlight tour, which kinda sucked, then on the Earthling tour, in a way smaller venue, and it rocked. I took a wrong turn on my way to the can and found myself beside the stage. That really was cool....
