Next to the symphonic repertoire, Karel has a great love for opera. After his debut in 2016 with Puccini’s La Bohème at Opera Zuid (the Netherlands), he was re-invited to conduct Un Ballo in Maschera by Verdi and the price-winning production of Bernstein’s A Quiet Place. At the Dutch National Opera Academy he conducted Britten’s The Rape of Lucretia and the highly acclaimed Dutch première of Mark Adamo’s Little Women.

In the next seasons he will make his debut at the Dutch Reisopera (Humperdinck – Hänsel und Gretel), the Liverpool Philharmonic Orchestra, L’Opéra de Toulon (Cosi fan Tutte) et l’orchestra de Cannes.

In the current season, a highlight was his successful debut at Opera Ballet Vlaanderen with the highly acclaimed production of Kurt Weill’s Der Silbersee. He will also make his debut with the Borusan Istanbul Philharmonic Orchestra, L’Orchestre de Chambre de Lausanne and the North Netherlands Orchestra. Karel will also return to Opera Zuid for Britten’s A Midsummer Night’s Dream and the National Orchestra of Belgium.
