On June 26, 2009, the band announced a "save the date" for a three-day festival on October 30 - November 1. Phish.com contained an animated map of the United States, and individual states were slowly removed from the map, leaving California. Confirming several rumors, the band announced that "Festival 8" would take place at the Empire Polo Fields in Indio, California. The band played eight sets over the three nights, including a musical costume on Halloween, The Rolling Stones' "Exile On Main Street" and an all acoustic set "at the crack of noon" the following day. Before the acoustic set, the crowd was served free coffee and figure-8-shaped donuts. The festival was filmed in HD 3D and portions of the festival were released in movie theaters across the United States as "Phish 3D." Members of the band Sharon Jones & The Dap-Kings joined the band on Halloween night to perform a number of songs."They were just as nervous as we were. When we stepped up there and did the first two songs—the first one was "Tumbling Dice," and the other one was "Sweet Virginia"—Trey looked up at us after we got through the first song and he gave us a wink," Jones said
