Yeah, I agree that both bands took music someplace new. But, my argument is not that this is why you should like the Beatles. I enjoy the songs and the music first and foremost, but then when you realize how they created that music given their limitations it becomes that much more impressive. Lets say you really love this painting: When you find out that it was made by a man with no hands it becomes even more impressive imo. First and foremost the art has to speak to you, but when you are a true fan of art you start to learn how it's made, what amps they use, what gauge of guitar strings etc. You start to hear "sounds" that are unique to them. A specific percussive sound etc. My guess is as a writer you are in tune with the writing process of some of your favorites. Right? That's context.
