I'd say Les Savy Fav are good on album but amazing live. Definitely worth checking out. Didn't see Sky Larkin, it was actually 3 stages and everything good clashed (they might have been on at the same time as LSF, not sure). Did get some albums though.
You should definitely check out Los Campesinos if you get chance, they're great live.
