Days after Dropkick Murphys lead singer Ken Casey tore his Achilles during a performance, he took one of the main stages at Louder Than Life wearing a boot on his right foot and a sneaker on his left.

This year, the Celtic-inspired rock band will be performing at Suburban Park Stage on Sunday, Aug. 25 at 8 p.m. The Dropkick Murphys have half a billion streams and sell out venues worldwide.
