Ah, I see. After reading further info on the double CD issue, it is stated that the "Halle Concert Arts Society" reissued the original IMP release. This is a good thing, now it will be an apple to apple comparison of our impressions of the interpretation. Some negotiation must have occurred with IMP (or whoever has the recording rights). Maybe the Halle Society will be able to manage to reissue some of the excellent Barbirolli recordings with the Halle.
