rarely go to concerts, unless i like the band/musician very much or if a friend is going& asks me to go& i like the band/musician enough (since most "concert" concerts are 1-2 hr drive from me).
my town does get some great traveling bands over& I go to local venues a lot though....so I guess I'll list concert propers that i've been to +whatever i consider to be semi-known/known around here.
the strokes+ muse -were in town, did a favor by buying ticket off friend's friend-- lacked wow factor, but i guess a hilariously stoned stroke lead singer& witnessing someone sneakily "slipping" off to lower level from the stadium w/out breaking his/her ankle and w/out being caught is worth it.
jason webley-- my fav of his was quite circus-y. involved a shovel,death mask, storybook, bottles w/ rocks, and a HUGE red tomato balloon into which a)his head first disappeared into and he proceeded to bob along-- think jack in the box on a much grander scale b)he completely disappeared in the balloon (yes, it's that big)
the yeah yeah yeahs
the arcade fire
They shoot horses (don't they)-- on kill rock stars
Baby Gramps-- amazing well known folk musician...and I think Pirates of Carribean soundtrack has something from him
Sonic Youth (daydream nation tour)-- best. concert. ever. unfortunately crap venue&staff that made everyone stay in their seats(that's right, *everyone* had seated tickets)& cleared off the aisle by yelling several times during the concert when dragging people one by one didn't work out that well.
still awesome, but would have been s*** awesome if we could stay in the pit
