For the first “regular” show of “Unnatural Acts of Opera,” La Cieca presents Shirley Verrett in Act One of Verdi’s Macbeth in a live (and lively!) performance from La Scala, the opening night of the 1975 season. This was surely one of the greatest nights of Verrett’s career, when Kunst and Stimm met in perfect conjunction. And this is by no means a one-woman show — in the title role we will hear Piero Cappuccilli. Rounding out the cast are Franco Tagliavini as Macduff and Nicolai Ghiaurov as Banquo. This live performance was led by Claudio Abbado. For more details and to hear the performance, visit Unnatural Acts of Opera.
