We’ve been hearing for a while that Arcade Fire was amongst another stellar line up in PBS’ Austin City Limits program for 2011/2012. The concert was performed on September 17th, and the video dudes (and dudettes) have done all of their editing and mixing and what not. The show will be broadcast starting this weekend on your local PBS station. Click here to find out when your provider is going to air it. In the meantime, you can see the teaser video of “We Used To Wait” that has been leaked in anticipation of PBS’ biggest ratings hit in a while. Check it out below, and tune in this weekend to catch the whole thing. If you miss it for some reason, you can stream a large catalogue of ACL shows here.
