The Grateful Dead played more than 2,000 concerts, but none continues to spark interest and provoke discussion quite like the band’s performance at Cornell University’s Barton Hall on May 8, 1977. It is one of the most collected, traded, and debated concerts by any band ever, has topped numerous fan polls through the years, and was a favorite of the group’s longtime archivist Dick Latvala, who stated: “Enough can’t be said about this superb show.”
