The quality of this performance does much to disguise the weakness of the writing. The singers superimpose their lines with musicianly phrasing; and there's further compensation in the orchestration, especially from high horns and lyrical bassoons, beautifully played here. Michael Hofstetter deserves great credit for making less-than-vintage Gluck so enjoyable.

….the representation of his (Gluck’s) early and middle years is patchy. All the more fitting then, to be able to welcome a thoroughly satisfactory issue of Ezio….. It is greatly to the credit of countertenor Franco Fagioli,
who sings the part (Ezio, sung by the famous castrato Guadagni in the première) in this recording, that there is no sense of anticlimax: he produces firm, expressive singing, with delicacy where appropriate.
