Don't know how I overlooked that. I guess my earlier post wasn't clear enough. Anyway, we can't call that one "obscure".
I must admit I never heard of these "Landmarks," they seem to be a well known series. Anyhow, on the back of the Takes Charge disk, it says that "when Cannonball signed to Capitol records in 1963 he brought 7 master tapes from his Riverside days with him. This is one of a series of Capitol Jazz CDs making those early classics available again."
So, is this Landmark series based on these tapes? If so, it seems BN has plans for them.
