From 1974 to 1980, Cleveland hosted the largest recurring stadium rock show in the country—drawing up to 88,000 fans per concert. Led Zeppelin. The Rolling Stones. Pink Floyd. AC/DC. And even Cleveland’s own Michael Stanley Band. With WMMS fueling the hype and the city’s deep-rooted music history going back to Alan Freed, this was more than a concert series— It was proof that Cleveland didn’t just love rock. We helped build it.
