The breakout synth-pop stars behind 2009's Manners will arrive at Grant Park armed with a new batch of tunes from their just-released follow-up LP, Gossamer. The festival date took on extra significance for the band after they canceled several recent gigs for reasons relating to frontman Michael Angelakos' mental health. But they're still set for Lollapalooza – so get ready for some of the first-ever performances of Gossamer's Pixie Stix-fizzy pop.
