This was a huge 3 day music festival which actually ended up lasting four days because of the amount of people. Four men organized the music festival in order to get money to build a recording studio, but ended up deeply in debt. The four men were John Roberts, Joel Rosenman, Artie Kornfeld, and Michael Lang. After a lot of confusion the festival became free and the expected amount of 100,000 people became 500,000 people at the festival. Luckily nothing terrible happened to any mass of people.
