Today, Dave Grohl and The Foo Fighters announced their first U.S. concert in 19 months headlining Napa’s BottleRock festival. Also playing the festival will be Dave Grohl-approved acts Tom Petty & The Heartbreakers and Silversun Pickups, as well as Maroon 5, Band Of Horses, Ani DiFranco, and Modest Mouse. It’s uncertain whether Grohl approves of the latter artists, but listeners should cautiously avoid listening to them until Grohl deems them essential.
