The recent news of Angela Gheorghiu’s impending divorce from Roberto Alagna may give some clue as to why this performance, part of the South Bank’s second ‘International Voices’ season, was postponed from its planned date of 2nd October. In the interim she has also, in the role of her accompanying tenor, swapped the American up-and-comer James Valenti, due to co-star with her in next year’s Covent Garden La Traviata, for her compatriot Marius Manea, who she has performed with several times already this year. The conductor Ion Marin made it three out of three for Romanians in the principal roles of the evening, here conducting the Philharmonia.
