Arthaus Musik offers a 1967 “Le Nozze di Figaro” (The Marriage of Figaro) that to some extent can be labeled “historic.” For one thing, it’s sung in German, not Italian, but also is one of the earliest relics of full-length opera produced for television. In full, if occasionally faded color (overall the remastering is quite fine), the most notable aspect is that the entire cast was part of the Hamburg State Opera. Tom Krause sings Count Almaviva, in the same year that his international career really took off with his Metropolitan Opera debut. The other casting highlight was the then-29 year old Edith Mathis as Susanna. Not perhaps the first choice for those new to operas, even ones so central as “Figaro,” but worth seeking out for those who want to experience every aspect of Mozart interpretations.
