Do yourself a favor and get this CD now. It is indispensable.An amazing work If you are unfamiliar with alternate tonal scales or non-western music, be prepared for a shock. When I first heard the CD in the 80's, I hated it. I listened again, and again, and began to retune and understand. Now it is one of my favorite albums, definite in the top ten. If you have an ear to hear, give it a listen.
