History

Historical Context

Woodstock ’99, staged July 22-25 1999 on Rome, New York’s former Griffiss Air Force Base, drew roughly 220,000 fans and recorded 5,162 medical cases, three deaths, and widespread looting and fires. Organizer Michael Lang and promoter AEG Live faced lawsuits and $5 million in city cleanup costs, prompting cities to tighten festival contracts and require detailed weather-emergency plans for later events such as Chicago’s 2026 Lollapalooza.
