For three days in August 1969, half a million music lovers happily braved torrential rains, endured lack of food and clean water, and grooved to the cosmic blues of the Grateful Dead and Janis Joplin, danced all night to the funky soul of Sly and the Family Stone and witnessed the birth of a new band called Crosby, Stills, Nash and Young. Held at Max Yasgur's dairy farm in Bethel, N.Y., the first Aquarian Exposition, or the Woodstock Music & Art Fair, grew far beyond the expectations of its creators. In this lively memoir, Lang, one of the festival's cocreators, retells the storysome of it already well-knownof the halting steps that he and his partners took to develop the greatest rock concert of all time. After a stint at NYU, Lang moved to Coconut Grove, where he opened a head shop and, with the help of some of his friends, organized Miami Pop in 1968, one of the first outdoor music festivals drawing major acts. Burned out on Miami, Lang headed to Woodstock, N.Y., to settle into the bohemian community of artists and craftsmen, and opened a recording studio. With a storyteller's verve and energy, Lang regales us with the tales of struggles with smalltown political leaders who opposed the festival, the kindness of Max Yasgur and the gargantuan task of feeding and taking care of a community the size of a large city. With the gritty insights of the ultimate insider, Lang weaves interviews with performers and others into his memoir, providing a glimpse of the madness, frustration, happiness and sheer euphoria that turned Woodstock into a memorable music festival.
