Trove Thursday uncovered two broadcasts of Donizetti’s Lucrezia Borgia that share a fascinating nexus: in each an enduring superstar tenor—José Carreras/Alfredo Kraus—is poisoned by a soon-to-vanish rising-star soprano—Vasso Papantoniou/Margarita Castro-Alberty.

Trove Thursday relishes neglected works, operas in translation and irreplaceable divas, and this week it presents a pair that embody all three affections: Cherubini’s Les Abencérages and Weber’s Oberon in Italian with the glorious Anita Cerquetti, conducted by Carlo Maria Giulini and Vittorio Gui respectively.

A broadcast of Weill and Brecht’s pungent Die Dreigroschenoper
