All of the principals here appear in other Opera Depot releases of this opera. They're all in good shape though I prefer some of their other performances. Leinsdorf sounds determined to get through the opera as quickly as possible. His tempi are quick and to the point, he never lingers. Buenos Aires wasn't used to uncut Wagner in those days (1969) so there are substantial chunks of music cut from each act, most of them centering on Gurnemanz's lengthy monologues. In Act Two there is a sizable chunk of the Klingsor/Kundry scene cut as well as a portion of the Kundry/Parsifal scene. Act Three finds a cut of some of Gurnemanz's monologue early on, but since the time saved was only about three minutes one wonders why it was made at all.Windgassen still sounds good, if not youthful (he was nearly 60). Crespin sounds glamorous and seductive. Adam sounds more unsteady than I would've thought for 1969, but his superb diction carries the day. Crass sings the Good Friday scene beautifully with a ringing high E. The Flowermaidens make a mellifluous group.The sound is very good and the disc breaks intelligently chosen.For fans of the singers and those who prefer cut and fast Wagner.
