I am very grateful to have this despite the fact that this represents only chunks of an excellent performance. Yes, the voices are recessed, but not impossibly so; enough can be heard to make one regret the entire performance hasn't survived.The young Te Kanawa sings gloriously, floating a perfect trill in the "Plebe! Patrizi!" ensemble. Conductor John Matheson doesn't take the traditional cut in the Act Two trio for Boccanegra, Amelia, and Adorno so we get to hear Te Kanawa's shining top C twice. Mauro is heard in his big aria and sings it so well he receives a hearty "Bravo!" from someone in the audience. Glossop and Christoff are both great; a pity their Act 3 confrontation was lost or not recorded (there are no excerpts from Act 3). Allen is heard briefly, but we hear his ringing top G in what's left of Act 2. The Act 1 Adorno/Fiesco duet is heard out of order (it's placed after the Amelia/Boccanegra duet), but it's tracked separately so one can easily fix that.This isn't for casual listening, but fans of the singers will enjoy this.
