That's a great bargain. The mastering by Joe Tarantino, however, is uncharacteristically loud, imo. You can't crank this up like you can OJCs. Very irritating. His work on the Coltrane Fearless Leader box from just after is much better and not tiring at all. I once saw one Amazon reviewer mistaking this Miles Davis box for RVG remastering, too lazy to read the booklet, but going by the loudness alone I cannot blame him. Every thing else by Joe Tarantino I like (16bit OJCs, 24bit OJCs, box sets, etc.).
