Richard Wagner's works are featured in multiple international performances, including 'Tristan und Isolde' at the Radio France Festival in Montpellier and staged productions of 'Die Walküre', 'Götterdämmerung', 'Siegfried', and 'Das Rheingold' in Munich, Sopot, and Budapest. Meanwhile, controversy persists over Wagner's antisemitism at the Bayreuth Festival, while a more personal side of his music is explored in a concert by the National Orchestra of Lille.
