Some good points from Big Beat Steve and David, but back to the thread.
I don't believe potential purchasers of the Gryce set have a lot to worry about. The Garland four cd set comes in a double four cd jewel box and while there are no notes you do get full lineups and recording dates. Sound seems fine to my old ears and on my modest system. If you need this music then this isn't a bad way to get it.
