Adrian Grenier, himself a member of two New York bands -- Kid Friendly and The Honey Brothers -- is taking ET inside the Firefly Music Festival this past weekend in Dover, Delaware, which featured amazing bands like the Red Hot Chili Peppers, Foster the People, Vampire Weekend and Public Enemy just to name a few.
The Entourage star attended the festival on Saturday and Sunday and checked out shows by Kendrick Lamar, Tom Petty and the Heartbreakers and more, as well as hung out in the VIP lounge and the artist compound with members of The Skins, a band he manages.
