Its style falls a good distance from the historical niceties of our modern era’s historically informed performance standards, but yet it still lands squarely in the most enjoyable listen category. Sir Colin Davis is near the beginning of his brilliant career to come when this Glyndebourne Festival live 1960 production of Mozart’s Die Zauberflöte was staged. He leads a cast including Richard Lewis, Pilar Lorengar, Heather Harper, Geraint Evans and Hungarian bass Mihaly Szekely as Sarastro, whose formidable presence on opera house stages had been overwhelming audiences since the 1920s.

From the private collection of the late, great dramatic soprano Martha Mödl comes this 1955 live broadcast recording of Richard Wagner’s Die Walküre, captured in excellent MONO sound and differing from the Testament label Die Walküre release of the same year’s performance with the same conductor (Joseph Keilberth) in both its sound (stereo) and, ever so slightly, in cast, first and foremost in the case of Ms. Mödl as Brünnhilde, but both, of course, first-rate dream casts. The other glorious, featured voices from this production include Astrid Varnay, Ramon Vinay, Josef Greindl and Hans Hotter.
