I think what makes sense is a Betty Carter box of the 1970-1982 BetCar/Roulette sessions. The Verve sessions are all very easy to obtain, as are most if not all of her 50's-60's recordings. And both the Verve sessions and the 50's-60's sessions are different chapters than the BetCar sessions. No need to run up the size of the box at $17/disc, that limits the potential buyers. I would be OK with including the excellent and hard to find "Inside Betty Carter", so the box could be something like "The 1964-1982 Betty Carter Small Group Recordings", though the 1970-1982 box would be more focused.
