My pride and joy. The centerpiece of my collection. At almost 1000$US, it should be. I had been looking for this for two years and wound up with a mint condition, signed copy. I absolutely love this work. It is soothing, complex and rewarding at every listen. It is basically Young playing solo piano, tuned according to just intonation, for approximately five hours. The changes in chords are slow and almost imperceptible (unless you understand just intonation). No matter which level of understanding you have of this recording, there is something magical about it. The box exists also in a cassette and LP edition. The five CDs in this box are without extra covers and are placed in jewel cases and come with a large booklet. The "untitled" tracks are empty tracks which are supposed to be used when programming all five CDs to play without any breaks (on those old multi-CD players).
