The 2015 Foo Fighters show at RFK Stadium marked the 20th anniversary of their self-titled debut, and the July 4th concert featured supporting acts by legends of their own right including Joan Jett and the Blackhearts, Gary Clark Jr., Heart, LL Cool J, and Buddy Guy. The show was a star-studded line up that Dave Grohl and the Foo Fighters headlined, despite Grohl’s recent broken leg injury that (tried to) contain him to a seat. The energy of the Foo Fighters is undeniable, and Mountain Productions proudly provided the main stage and supporting equipment for the event.

Mountain Productions’ Mountain Truss HD System was built with audio support in the field from two of Mountain’s delay towers, each supporting three spot baskets. A long downstage thrust was built on the main stage that kept performances up close and personal with the audience.
