The WaterWheel Foundation will mark their 15th Anniversary with a special pre-show celebration before Phish’s August 18 performance at San Francisco, CA’s Bill Graham Civic Auditorium. Slated to take place at the Civic Auditorium at 5 PM, the event will include complimentary beer, wine, sandwiches and snacks as well as a WaterWheel 15th Anniversary Poster by Jim Pollock (limited run of 350). Fans who purchase tickets to the show will also gain early entrance into the concert venue. The WaterWheel Foundation recently celebrated their 15th Anniversary with an East Coast party at Saratoga Springs, NY’s Putnam Den during Phish’s SPAC run.
