Not sure which category this fits in, but just announced today is this from NPR:

If you don't want to go to the link, this is a jazz concert recorded in 1957 by Voice of America but never broadcast. Now it is for sale! One must wonder about the legal issues behind it all - and if anyone has any inside info on this it would be extremely interesting and cogent to the recent discussions...
