I think this is a very good set, it certainly SOUNDS fantastic as well. . . . I've just really become bored over the years with the actual lp itself. I mean I bought this on vinyl so very long ago, and it's very cool, but sort of hasn't held up for me over the years as a big favorite. I really enjoy this set for the other material: the material with Pascoal is really neat as I've always enjoyed the little snippets released before, and "The Mask" I just love, have always loved the thematic/material since I first bought "Miles at Fillmore"!
In my opinion nothing here quite matches the original "Bitches Brew" session material, BUT I prefer almost all of it to the extra material in that box set. Which is the reverse of my feelings about the Jack Johnson box!
