Performer: Mario Sofroniou

Alzira, Verdi’s eighth opera, is something of a discarded child within his canon, not least because of Verdi’s own dismissal of it as “proprio brutta” (really ugly) after it was poorly received both in Naples and Rome. Perhaps Verdi was stung by a blot on an otherwise successful career: on the basis of last night’s concert performance by Chelsea Opera Group, the score has plenty to commend it.
