At Theater an der Wien Stanisław Moniuszko’s Polish national opera Halka is performed by a superb cast including Corinne Winters ('devotedly') , Piotr Beczała ('vocally outstanding') and Tomasz Konieczny ('his acting is piercing') (Der Standard). The Polish leading team, above all director Mariusz Treliński, puts the plot into a supercooled crime aesthetic. The ORF Radio Symphonie-Orchester Wien under the baton of Łukasz Borowicz plays with perceptible delight.
