We're teaming up with our friends at Pop Montreal to co-present their amazing official SXSW showcase at one of our favorite Austin venues. Featuring, for starters, two of the absolute must-see acts of SXSW 2011: cosmic-pop prodigy Grimes and Arcade Fire-collaborator / force of nature Colin Stetson, who performed one of the most mind-blowing sets I've ever seen as support for AF's epic Big Sur show last fall. There's more, too: check all the details here, and view the full lineup after the jump...
