They call Cleveland, Ohio, “The Mistake by the Lake.” It’s an unfortunate nickname, stemming from their wretched winters, a river that has a tendency to catch fire, and a seemingly permanent place on any Most Miserable Places to Live in America list. But for as much guff as Cleveland takes, it is a rock and roll town, perhaps the rock and roll town. There’s more than one reason the Rock and Roll Hall of Fame is in Cleveland, and today we celebrate one of them: the very first rock concert, held in 1952.
