Summer Jam at Watkins Glen

This one-day concert took place on July 28, 1973, at the Watkins Glen Grand Prix Raceway in New York State, bringing together the Grateful Dead, the Allman Brothers Band and The Band on a single stage. The event drew an estimated 600,000 attendees, a record crowd for an outdoor music gathering in the United States, with only a fraction of those present having bought a ticket.
