I'm pretty sure that the Fantasy catalog has been bought by Concord. I'm not sure if that will change the availability of rights but it certainly changes who you'll ask. I don't know if you've ever looked at the full Fantasy catalog, but it's shocking how many jazz "greats" are in there.
I agree that some classic jazz would be fantastic ( hard bop please! ). I don't know if you guys have been watching the prices on ebay on quality jazz but it is insane! I got outbid on Coltrane's"Ballads" a few months ago and the winner outbid me by $100! Most of the ones I've bid on since then has resulted in the same trouncing. I guess that's why our own U47 has his Kind of Blue 2 track out there for a buy it now of $350. If it's a good copy, I don't think I'd let it go for much less.
