Spazzed-out Montreal indie greats the Unicorns, who broke up in 2004, hinted at a possible reunion earlier this year, but when we reported it, frontman (and Islands mastermind) Nick Thorburn emailed us and told us not to get our hopes up. Well, get your hopes up; Unicorns are officially back together. They’ve got a Twitter and everything. And as Pitchfork points out, they’ll open five dates for Arcade Fire in the month of August. They’ll play the Forum in Inglewood, California 8/1-2, and they’ll also open Arcade Fire’s three-night stand at Brooklyn’s Barclays Center 8/22-24. (Dan Deacon will also play all three shows.)
