More comparisons to report on my end: I compared an early Bitches Brew Lp to the recent version of Bitches Brew on CD (from the Complete Bitches Brew sessions set). Both were very good, very listenable. The Lp had a bit less bass, and the treble was softer, very natural, and easy on the ears. The soundstage was wide, and there was good midrange warmth. The CD, on the other hand, was as good as CDs get. As with the later Prestige release of Bag's Groove, described above, it was as if the engineers/producers recognized the ways in which CDs can annoy, and "tuned" the production to avoid that. The treble was crisper than the Lp, but not annoying. The bass on the CD was better grounded than the Lp. The soundstage was a hair narrower, but quite good, and the midrange was warm and cozy. The highs on CDs can sound somewhat artificial and "splatty" (to me)...there was almost none of that on this CD. Finally, if this CD was missing the detail of the Lp, it was not particularly noticeable. I just got caught up in the music. (What I did was started Pharoah's Dance on the Lp and CD at the same time, and just switched back and forth. Not very scientific, but good fun.)
