The main review is very helpful indeed, but one thing that should have been mentioned is that a lot of the ballet music is omitted, including the first Air gai and Lento (no. 7) after Clytemnestra's first aria (no. 6) and the Air gai from the no. 11 ballet, both in Act I. These are very familiar and well known melodies, and there are others omitted too. I made a tape with these numbers inserted from a recording of some of the Aulide ballet music. I got the recording because it was the best available, but we really need a COMPLETE recording of the opera. I doubt if Gardiner will come to the rescue, because his recent recording of Alceste omits most of the ballet music too. 　　I for one am really a fan of Gluck
