Nielsen's "Maskarade" is regarded as Denmark's national opera. It combines folk-song character, Mozartean elegance and virtuoso surprises to create what conductor Titus Engel describes as 'musical comedy that's both witty and of the highest calibre'. Based on an 18th-century play by Ludvig Holberg, the story revolves around Leander and Leonora who meet at a masquerade ball, swear undying love, and then have to deal with the complicated consequences of their situation, all accompanied by Nielsen's irresistibly sparkling score. This acclaimed contemporary staging from Oper Frankfurt is sung in a new German translation and directed by Tobias Kratzer.
