Phish was so popular that the band drew 70,000 to a decommissioned air force base in remote Plattsburgh, New York for a two-day Phish festival called The Clifford Ball. It was the largest rock concert of the year. Phish played seven sets over two days, one of which featured a jam atop a flatbed truck cruising through the campground in the middle of the night. The second day featured a symphony orchestra performing classical music in the mid-afternoon. MTV made a documentary of the experience."The Clifford Ball" was the first weekend-long festival hosted by Phish throughout their career. The event took place on August 16 and 17, 1996, at the former Plattsburgh Air Force Base in Plattsburgh, New York, about one hour west from Phish's home base of Burlington, Vermont. The event was named after Clifford Ball, a man who held events for aviators such as Amelia Earhart. "The Clifford Ball" was a proposed name for the 1990s traveling festival that ultimately was named H.O.R.D.E..
