Let’s jump ahead to later years. In 1994, Woodstock 94 was held and attracted a large audience, but the name casted an image for caution. 2019 was supposed to be the year of Woodstock 50. Only a handful of original performers, the youngest in their seventies, would be around, but it would have been a very ceremonial presentation. But the name presents a risk, so there won’t be one.
Move only five years after Woodstock to 1974 and you have the Ozark Music Festival. It was ranked by many as “second only to Woodstock” yet it was nearly forgotten after it ended. Developers promised 50,000 tickets would be sold and booked the Missouri State Fair Grounds in Sedalia. When the event came in July, three to six times that many people showed up (sound familiar). While Yasgur’s farm returned to its farm status after Woodstock in New York, the Missouri fairgrounds were an exhibition facility that had to be cleaned up quickly for the state fair. Professional recordings became the basis for a movie about Woodstock, but such recordings from Ozark were confiscated as evidence for fraud. The only remaining records are YouTube slide shows and a few pieces of 8 mm movie.

So, we see strong evidence for aversion to multi-day art and rock concerts. But a more recent trend might open the doors. Several communities are have been organizing Fuzz Fest, a three-day camping-concert event. Few book any artists of fame, they are just local events. Attendance figures are more in the range of 15,000. Can this be the future of outdoor camping concerts?
