Foo Fighters returned to the stage in D.C. on 4th of July to not only celebrate the countries independence but the bands 20th anniversary. It was the bands first outing since Dave Grohl broke his leg after falling off stage. Still in a cast, Grohl took to the stage in a giant throne, surrounded by guitars, lights, amps, and pure epicness, so he could perform whilst resting his injured leg. His broken leg didn't hold him back from rocking out, and even though seated the entire show was filled with high energy. Check out footage of their performance at the Robert F. Kennedy Memorial Stadium.
