Now that Phish have firmly established their comeback, both to the stage (via a sold-out summer tour) and to the studio (their new album 'Joy' debuted at No. 4 on the Billboard rock chart), the band is prepping to bring back two of their most beloved traditions simultaneously at the end of October. As previously reported, Phish's Festival 8 will be held in Indio, Calif. at the site of Coachella from Oct. 30 to Nov. 1. It combines Phish's tradition of covering a classic album in its entirety as a sort-of musical Halloween costume with the band's affinity for throwing large-scale festivals featuring just themselves on the lineup.

It was always understood, amongst their fervid followers anyway, that one of the Saturday sets would carry on the band's Halloween tradition. The band has now announced another unusual performance that weekend: an all-acoustic set on Sunday at "the crack of noon." In typical Phish fashion, coffee and donuts will be served for both the bleary-eyed and the red-eyed.

In a recent interview with Time Out New York, frontman Trey Anastasio was tight-lipped about what album Phish will end up covering on Halloween. "The only clue I can give you is that it's an album I truly love," he said. "I can't wait."

Neither can 50,000 Phishheads, many of which have posted their own speculative theory somewhere on the internet.
