Each Saturday, on radio 3's programme CD Review, the available [in the u.k.] versions of a work are compared in the Building a Library segment [except during the summer when the Proms are on.]
Next Saturday, the work so treated is M's D.L.E.
Performances get steadily discarded throughout until there's either an out right library choice, tho there's sometimes room for a bargain-price choice, and a historical ditto.
The prog should be available from BBC iPlayer for 7 days after the broadcast.
