The performance always deserved the highest of ratings but EMI hasn't done this one justice.This is a much better engineering effort on the part of EMI than the really horrible edition they published to commemorate the 25th anniversary of Callas' death. The slip case is classy, so is the libretto and it comes with two post cards of Callas. But once again EMI has screwed up. The recording is pitched incorrectly coming in a little flat.I'm so sorry I sold off the original CD edition which contained tape hiss but was much brighter in sound than any of these state-of-the-art reproductions.
