Dave Grohl will host, direct, and produce a new documentary series with HBO that will see the Foo Fighters frontman visit a number of legendary recording studios across the US. Grohl describes the project as \a love letter to the history of American music,\ and its essentially a continuation of the work he started in last years Sound City documentary — which currently carries a 100 percent rating at Rotten Tomatoes. At every stop along his studio tour, Grohl recorded a new song with another famous, \local legend\ musician. The guest list includes Kiss Paul Stanley, Joe Walsh of The Eagles, and Hearts Nancy Wilson.
