Analog, Columbia has plans to release six cds of the Cellar Door material, the cds are all sequenced and mixed and ready to print. I don't think they would be happy about this! I'm not pointing fingers really because my hands aren't clean, but the Miles Davis estate has been blocking the sales of all kinds of bootleg cds of Miles material, they would not be happy with this site even if Columbia weren't about to launch cd sales of the material sometime in the next year.
Frank Zappa had actually issued an entire series of cds called I think "Ban the Boots"---bootlegs done officially in a special series. I don't know what the sales figures were, but it was done (I'm not much of a Zappa fan so I didn't follow the material closely). I don't think their estate will like this website much either.
