Wow!! High energy doesn't cover it!! "....uniqueness" is well chosen!
I didn't know what to make of Arcade Fire - I can't really dislike a rowdy band with two violins, a bullhorn and a lady drumming while dressed kinda like an ee-gyp-shee-un, and I admire their ability to have two bicyclists circling the stage and not kill one with the boom camera, although it looked close a couple of times. However, one number from them was plenty. I feel like I watched a loud rock concert, car wreck and police car stop all in one number.
