I can understand how you might not dig Electric Byrd, Jim. Reading your comments, what came to mind immediately is another BIG difference between Bitches Brew and Electric Byrd: Miles' solos are electrifying and Byrd's are not. ... Then again, it's not really a soloist's record; it's a texture record. (Or, like you say, a "mood" record.) I dig the album's wash of color, its Brazilianisms and arrangements. Airto and Duke P.
And Mickey Roker sounds really good too. Didn't say anything about him in the post, and I should've.
... Not at all trying to convince. Just more chatting at the bar over our beers (metaphorically speaking).
