not that it has anything to do with stay notes ... but, when I first purchased the set years ago I transferred some onto cassette for the car.
Funny thing was that the first few songs from disc one (quartet sessions) had a rumble and whirr OVER the music that ended when the first few songs did - not the deck, tried different tapes, became obsessed - Mosaic sent a replacement and it did the same. weird but the disc itself played fine and this anomaly was only apparent when on a cassette.
