The Moondog Coronation Ball was a concert held at the Cleveland Arena in Cleveland, Ohio, on March 21, 1952. It is generally accepted as the first major rock and roll concert. Background Alan Freed "had joined WJW [-Radio] in 1951 as the host of a classical-music program, but he took up a different kind of music at the suggestion of Cleveland record-store owner Leo Mintz, who had noted with great interest the growing popularity, among young customers of all races, of rhythm-and-blues records by black musicians", according to the "History" website. Mintz decided to sponsor Freed's three hours of late-night programming.

Freed made a public apology on WJW the next day; he referred to the event as the "ball" or "dance," not as a "concert." Accounts in the contemporary Cleveland newspapers are at odds with lore that circulates today about the event, scheduled to begin at 10 p.m. “The frustrated gathered outside, unable to buy a ticket at $1.75, their number increasing until it amounted to about 6,000” as estimated by Cleveland Police captain William Zimmerman. “About 9:30 they stormed the Arena, knocking down four panel doors, brushing police away and storming inside.
