Arcade Fire - I've seen them four times, always great.
Caravan Palace - They played last summer at the Calgary Folk Fest. Great set, lots of fun and dancing. High priority for me.
Chromeo - Fun, a good time, but not a priority.
City and Colour - Worth seeing, but I won't be upset if I miss it.
Fatboy Slim - Great at the time, but it's been many years, so I can't comment on his current show.
Muse - Cool stage show, so-so music. I'll probably see them.
QotSA - Awesome.
