The US Festivals (US pronounced like the pronoun, not as initials) were two early 1980s music and culture festivals sponsored by Steve Wozniak, formerly of Apple Computer. The first was held Labor Day weekend in September 1982 and the second was Memorial Day weekend in May 1983. Wozniak paid for the bulldozing and construction of a new open-air field venue as well as the construction of an enormous state-of-the-art temporary stage at Glen Helen Regional Park near Devore, San Bernardino, California. (This site was later to become home to Blockbuster Pavilion—now San Manuel Amphitheater—the largest amphitheatre in the United States as of 2007.) The festival stage has resided at Disneyland in Anaheim since 1985, and has operated under various names and functions as the Videopolis dance club, the Videopolis Theatre, and the Fantasyland
