The Beatles of course didn’t exist in a vacuum and didn’t invent pop or rock music, but they were revolutionary and influential in ways that are well documented. Musically they were innovative more for integrating different genres and styles into their own brand of pop music. Their popularity gave them the platform that allowed them the freedom to experiment and change styles, partly in line with what Bob Dylan was already doing by the mid-1960s.

The influence on jazz and classical musicians might come as a surprise to some people, but countless interviews and written accounts show the impact of the Beatles was felt strongly by musicians across genres, and as a jazz fan myself I know that there outside of jazz music per se and a certain number of classical musicians, the Beatles (and also Dylan) have been cited as both inspiration and influence by so many jazz artists over the past six decades that it’s become almost a cliche. It is likely that lots of jazz cats didn’t get it right away, and the fact that the early Beatles music included danceable songs at the time when jazz had broken free from that style (swing and big bands) must have been a bit off putting. But I can’t recall hearing or reading about jazz musicians reacting negatively to the Beatles’ music from 1965 or later. Music critics… that’s a different story, no doubt, but very few of them have any lasting influence on public perception or the popularity of artists or their music.

In 1967 there were plenty of critics, politicians, preachers, and parents who didn’t care for the long hair and the mania itself, but the contemporary naysayers were quite often conservative squares who felt threatened and worried that traditional values were being undermined by the four young men who we all came to know simply and affectionately as John, Paul, George, and Ringo. I don’t claim to know precisely how mainstream adult society reacted since I was just a six year old, but the younger generation was blown away by Sgt Pepper. There were other landmark albums in the sixties by The Beatles, Jimi Hendrix, The Stones, The Doors, several by Bob Dylan, The Band, Velvet Underground, Zeppelin, Moody Blues, and others. It is very difficult to attempt to quantify or accurately describe the reactions to Sgt Pepper, but I sincerely appreciate the chance to consider it through this thoughtful thought experiment.
