This weeks "Picking up the Slack for MTV" is not exactly a music video, but a video made for the band by a fan of Broken Social Scene.  This video was made in response to the G20 Summit in Toronto, June 2010.  The creator, who wishes to remain anonymous, put together a very powerful and moving mash up with BSS song "Meet Me I The Basement" as it's anthem.  I found this video to be extremely well done and hope that you might as well.
