Live, Video: Kritiken zu klassischen Konzerten, Opern, Ballett und Tanz finden | Francisco Javier Borda

Putting on a Ring cycle is normally considered a major undertaking for any opera company. For a mid-sized provincial opera company, the idea of staging the whole cycle in a weekend seems barely short of insane. But that’s what Opéra de Dijon are doing – Das Rheingold and Die Walküre last night, Siegfried and Götterdämmerung tonight, and it just had to be seen.

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.

After their Mascagni debut last year, with L’amico Fritz (the composer’s first post-Cavalleria opera), Opera Holland Park have set out to uncover more music from the so-called ‘one-hit-wonder’ – still known to most for his smash verismo opera alone.
