Metz gave an ass-kicking performance of the songs "Dirty Shirt" and "Can't Understand" during their set at the Pitchfork Music Festival last Saturday afternoon. "Dirty Shirt" is a single the band released in 2012, and "Can't Understand" was released last month as an Adult Swim single. Their live performance, however, is a force to be reckoned with. The crowd went wild for the Toronto-based trio's raucous brand of high-energy, high-volume hardcore punk. Check out it out in the videos above.
