Concert performances of operas can fail to make an impact, lacking the dramatic intensity a successful stage performance brings. Here though, perhaps without a production to distract from the purely musical, Nelsons galvanises a near-perfect cast into one of the most successful performances on record. In tremendous voice, Opolais captures the complexity of Angelica’s situation, and Braun –¬†a fine Wagnerian¬†– is both imperious and identifiably human. With full texts and translations and excellent recorded sound, this is warmly recommended.
