You are correct. It's a great album. The Dual Disc claims to be surround sound, but it actually 3 channel.Jaybird, you're confusing this with Miles Davis' landmark album KIND OF BLUE. This album AFAIK is brand new and has never been released before. It's actually a precursor to KIND OF BLUE. I only wish Analogue Productions had released it in it's original THREE CHANNEL CONFIGURATION instead of mixing it down to 2 channels!
