Just as Richard Strauss' wistful heroine, the Marschallin, mourns the passing of time, so will opera lovers echo her lament in this telecast of Der Rosenkavalier, which returns at 8 tonight on WHYY-TV (Channel 12) for the first time since its original airing in 1982.
Only a few years ago, the principal singers - Kiri Te Kanawa, Tatiana Troyanos, Judith Blegen, Luciano Pavarotti and Kurt Moll - were everywhere. Now, they're either winding down their careers or gone. Lucky that this video exists, then, because this opera about romantic intrigue among Viennese aristocracy isn't just full of luscious singing (except for Pavarotti, who's ill at ease as the Italian singer), but is also crackling good theater.
