This was one of the first Miles albums I ever bought. Plan 9 Records in Midlothian, VA used to carry Miles Davis Sony Japan CDs. I bought Them up over time, but this was one of the first, and remains a favorite. I'm sure I've gushed about it ether here or bnbb in the past. A good friend also had Supernova back then. I finally found a copy of my own this past year. Really great to hear the difference in the way this music is approached. Is any of this material also on Speak Like A Child? I can't remember.
