Dave Grohl and the Foo Fighters packed over 20,000 fans into sold out Centennial Olympic Park Sunday night, October 4, 2015, with Gary Clark, Jr. opening the show. The light rain couldn't dampen the energy and spirit of the huge crowd. Grohl, who broke his leg while performing in Sweden in June, rocked out in a motorized throne, which was equipped with lights and carried numerous guitars. Robb D. Cohen/ RobbsPhotos.com
