One thing that may turn some people off Bitches Brew it how the drums are recorded fairly distant sounding. Bringing them more up front would go a long way to making it less abstract sounding, letting groove oriented people get more out of it. When I first listened to it, it just sounded very random & jammy, which I can appreciate sometimes, but it's hardly what most people would consider accessible. The more I listened to it, the more I heard the structure, which is there, as much as the grooves are there, but it's long form, not verse chorus verse.
