Woodstock was put on by Michael Lang, Artie Kornfeld, John Roberts and Joel Rosenman. Roberts was the financer, backed by a trust fund; his friend Rosenman, a graduate of Yale Law, was an amateur guitarist. Their friends were Kornfeld, vice-president at Capitol Records, and Michael Lang. Lang was a light-hearted hippie who had owned a head shop, and hoped to build a studio in the Woodstock area to serve singers such as Bob Dylan and Janis Joplin, who had homes nearby. When Lang and Kornfeld told the idea to Rosenman and Roberts, Rosenman got the idea of a rock concert with the same musicians. They picked the slogan "Three Days of Peace and Music". They hired artist Arnold Skolnick to design the artwork for the poster with the bird. It wasn't until years later, after the release of the 3-LP album and the documentary-like movie that the original investors began to recoup their investment.
