it may be the more challenging one, but it's really worth it, seeing as it helped shaped jazz music afterwarRAB with some of the things they did on there. it may sound weird, but with Bitches Brew, once you get it, you really get it
i'm listening to Kind of Blue right now, Blue in Green atm, and i'm starting to agree with Satch on this one. as a regular jazz album it's pretty solid, but as one of the greatest? eh, maybe.
