Today marks the 60th anniversary of what is widely considered the first Rock & Roll concert, DJ Alan Freed's deliciously monikered "Moondog Coronation Ball." The concert (co-produced by local record store owner Leo Mintz) was another testament to the underrated importance of Ohio in the development of Rock & Roll, taking place in Cleveland at the Cleveland Arena, which hosted hockey and basketball games (it was demolished in 1977). Freed, of course, was the great Cleveland DJ (and "King of the Moondogers") who was crucial in the popularization of Rock & Roll, introducing both the genre's name and the music to the world through his radio program on AM station WJW. In an era when segregation was very much prevalent in society, the Moondog Coronation Ball drew attention for its unsegregated bill, featuring both black and white performers, as well as welcoming both black and white fans to attend. (Freed's black fans were reportedly shocked to discover at the concert that the DJ was actually white.) The popularity of this new-fangled Rock & Roll music became apparent the evening of the show when wwaaaaayyy more people showed up for the concert than the arena could accommodate. The arena held just under 10,000 people, but 20,000 turned up, partly due to additional tickets being accidentally printed. Fans stormed the gates, overcrowding the arena and leading the media to call it a "riot" (adding to Rock & Roll's reputation for being "dangerous," which only made it more popular). The Moondog Coronation Ball is still held today, though the excitement level, of course, is a little more muted. Read more about that historic concert from the BBC (which declares that the Moondog event "laid the foundations for every rock gig that followed, from Woodstock to Glastonbury") here. Here's a clip from a documentary about Freed (the concert is discussed at around the 4:30 mark) by fellow DJ Frank Allan.
