And when did popular bands stop giving shows? It’s like this: looking over posters, ticket stubs, and other memorabilia from the first ten years or so of rock and roll, you see that they didn’t do concerts, but rather shows. It might be the Buddy Holly Show or the Elvis Presley Show, and I think it was the same for R&B performers as well. I think the Beatles’ performances were still denominated “shows” in this way. I don’t know if that’s how the fans actually referred to the events, but that’s how it was in the publicity and advertising.
According to the Google Ngram viewer, the usage of “rock concert” begins in earnest sometime in the year 1964 and spikes up thereafter like the end of a hockey stick. For me, having been born in 1958, “rock concert” has always been the standard form, with the shorter form “concert” applicable to pretty much any kind of musical performance.
How did this change come about? I do remember that there were a few years around this time when performers and fans preferred the term “rock” to “rock and roll”, presumably because the longer term connoted hokey images of greasily pompadoured guys spinning their poodle-skirted girlfriends around the dance floor. Elvis Presley was rock and roll, but Eric Clapton was rock. “Shows” were show business, like Dean Martin or Bing Crosby, but “concerts” were for serious music, or music with a message. So perhaps there was a conscious effort to elevate the image of rock by adopting some of the phraseology used with classical music?
Or something else?
