Fucked Up: Like Mastodon and Boris before them, epic Toronto hardcore outfit Fucked Up will be responsible for bringing some gnarly aggression to an otherwise relatively mild-mannered weekend of bands (the Jesus Lizard excepted, of course). While they’re best appreciated in a small, crowded space under dangerous conditions, their wall-of-sound live approach should serve them well even on a huge festival stage. Circle pits have been making a comeback with punk kids, and I will be seriously disappointed if I don’t see one during their set.

Matt & Kim: Though they won’t be able to match the six-deep Fucked Up crew in terms of sonic fury, Matt & Kim can whip seemingly any crowd into a stupid-happy froth and are likely to inspire just as much reckless dancing (I’m hoping for another circle pit).

M83: Not surprising.
