The Moondog Coronation Ball was kind of a disaster. It ended in a riot. One person was stabbed. But it was also the first public indication of how hot this new rock and roll trend had become. Organizers originally hoped for about 10,000 people. Twice that number showed up.

The Ball was the idea of Alan Freed, the Cleveland disc jockey who first coined the phrase “rock and roll.” He’s the reason Cleveland is home to the Rock and Roll Hall of Fame and Museum. And every time you find yourself in a packed concert venue, listening to music that’s a little too loud and a little too fast, you’re taking part in a tradition that began in Cleveland at the Moondog Coronation Ball.

Officially, the anniversary was on Wednesday. But the Ball was held on a Friday, and right now it’s almost quittin time across the Midwest.

So go have a Ball, in honor of Alan Freed.
