I did underline that it was my own personal opinion. Whatever contribution they made has mostly made the stagnated genre of pop music and the simple musical structures that go with it. But as I also said they did have some influence on bands that went on to make far more interesting things.
The end result is that when I listen to King Crimson (1969) I hear what I would still call creative and interesting music), when I hear The Beatles I hear what has become the stagnant and simplistic pop music, in particular pop rock. You might consider that a tremendous influence and you would be right I guess, I just do not see pop music as anything to celebrate.
I must disagree here. I think pop music is inherently less valuable than many other forms of music that I view are more serious (without me necessarily being a fan of all those genres).
I would liken it to comparing James Cameron to someone like Andrei Tarkovsky. Cameron movies may have been seen by infinitely more people and has to be recognized by a historian of movies. That does not put Tarkovsky and Cameron on the same level in my opinion. One makes movies as entertainment, the other made it as art. They are not mutually exclusive either.
Music is a very vague term in this context. If what is popular gets to define music, then yes that is true. I would however claim that the masters of jazz (as an example, they are not the only ones) have had a far more profound influence on creative music and what I would call quality music today.
It is also important to note that much of the point of my post was to underline that Beatles role in musical history is overdone to the point where it overshadows other equally important contributions. It was not my point that The Beatles made no contribution, I explicitily said otherwise.
I agree with a lot of your observations, here, but I think you're short-changing the 'pop music' genre to some degree.
Keep in mind that 'pop' is an extremely difficult genre to be creative, in. As you pointed out, the structures and expectations of a pop song are very simple and very limited. And add to that, the huge number of entries into the field at any given time. To be consistently good at writing, arranging and performing in the pop genre is probably the single most difficult endeavor of all fields of music. It's why someone like Michael Jackson is so amazing, even if you don't necessarily like his music all that much. He found a way to be unique, danceable, life-affirming, and universally apropos in a medium that we would have every reason to think has been long since completely played out. That takes real creative vision.
I am not a fan of 'pop' music, for the most part. But every now and then someone comes along that manages to bust that very shallow, way over-used genre of music wide open, again. As I said, Michael Jackson was one. And there can be no doubt that the early Beatles were another. They were a 'pop' band back then, and they weren't pretending to be otherwise. But they did it so well, and so consistently well, that they eventually became a sort of genre unto themselves. And it was then that they were able to really begin to explore some new musical boundaries, and still get played on the air.
It was the doors they opened with albums like Sargent Pepper and Abby Road that made way for so many of the bands that you and I have come to appreciate as not being 'pop'. These other categories of more experimental music didn't even exist until the Beatles made them possible. Not on the air, anyway. And they couldn't have done so without their early excellence in the genre of radio 'pop'.
If you don't believe me, just read what virtually every musician that you respect has to say about the Beatles. You'll find almost no detractors among them.
