Let's begin with what the extended excerpts are on these two discs:No prelude, no "Celeste Aida".Act 1, s.1 - begins with Amneris' "Quale insolita gioia" and goes through the end of the scene. No Temple Scene. Act 2, s.1 - complete Act 2, s.2 - begins at the Kings's "Salvator della patria" and goes through end of the scene.Act 3 - complete Act 4, s.1: from beginning almost to the end of the scene, but fades out before Amneris' "Empia razza!"; no Tomb Scene.Anything with Pauline Tinsley is worth hearing. Her accounts of Aida's two big arias are marvelous; she has no difficulty attaining the top C in "O patria mia". Her scenes with Amonasro and Radames show her keen imagination and spontaneous response to the text. Janet Coster is just as fine as Amneris, really lording it over Aida in Act 2, and then thrilling us with her ringing high B-flats in Act 4, s.1. What a crying shame the tape ran out before the end of the scene! Jan Derksen demonstrates again why he was considered a Verdi specialist in Holland. His Amonasro is not only well-sung, but devious and cruel. João Gibin is an excellent Radames, sadly deprived of his big aria in this recording. The sound is just this side of tolerable, but is pitched correctly.Recommended to fans of the singers.

Prelude, Act 1 scene 1 beginning (incl. "Celeste Aida"), scene 2, Act 2 till "Salvator delle patria", Act 4 scene 1 from "Radamès è deciso" and scene 2 (Tomb-scene) are missing, so the recording is far from complete. The cast is incomplete too: Tine van Grootel (Sacerdotessa) and Jan Blinkhof (Un Messagero) are not listed. The choirs have been Nederlands Operakoor (Dutch Opera Choir) and Jongenskoor van de Kathedraal St. Bavo (Boys Choir St. Bavo Cathedral) Haarlem, the orchestras Rotterdams Philharmonisch Orkest (Rotterdam Philharmonic) and Koninklijke Militaire Kapel (Royal Military Band). The hall: Theater Carré, Amsterdam. See https://opera-archief.nl/index.php/14-de-nederlandse-operastichting-1965-1986/968-aida-7273?highlight=WyJhaWRhIiwiYWlkYSdzIiwiJ2FpZGEnIl0=. The recording, obviously made by someone in the audience, has imbalance (cd 1 to the right, cd 2 in the middle and to the left), many disturbances and distortions e.g. by manipulating the microphone and the sound is very poor.
