Glyndebourne’s release of a live Rosenkavalier from 1965 longs to be loved and cherished by listeners.  Featuring a thrilling Traumcast composed of Montserrat Caballé, Otto Edelmann, Teresa Zylis-Gara, and Edith Mathis, one would certainly expect it to deserve much praise and admiration.  The sound quality is, however, a stunning disappointment.
