In his autobiography Opera Years Rolf Liebermann wrote: “Of all the film versions of operas in which I was involved, my favourite has always been Wozzeck, mainly because the interpreters and location were so convincingly authentic.” And truly, this film adoption of Alban Berg’s Wozzeck, recorded in 1970, fascinated with its constantly developing tension from the first tone to the last accord. Indeed the cast could not has been any better than in this production: Toni Blankenheim as Wozzeck and Sena Jurinac as Marie. Clearly and precisely in picture and speech, this film can truly be considered a classic and is now available on DVD for the first time.

From fairy tale to great opera: With Die Zauberflöte Mozart made the step from simple Singspiel to a full-blown German opera, thus laying the foundations for an independent opera culture in the German language. The 1973 Electrola recording combines a truly legendary vocal ensemble, featuring first and foremost Edda Moser, whom many people still regard as the best Queen of the Night of all time, Walter Berry as a Papageno oozing Viennese charm, Anneliese Rothenberger as the enchanting Pamina and Peter Schreier as her loving Tamino.

its many virtues include a formidable Queen of the Night in Luciana Serra, an adorable Pamina in Kathleen Battle, and vivid, primary-colour designs by David Hockney. James Levine paces everything to perfection.

Janowski's unfussy, clearly laid out performances, with the Dresden Staatskapelle on superlative form, may lack the sweep and energy of Solti's, or the compelling beauty of Karajan's, but they still have much to recommend them… Jessye Norman, then at the height of her vocal powers, is a rich-toned Sieglinde.
