Recent and upcoming season highlights include major appearances with both of his orchestras in leading European musical centers: the Vienna Konzerthaus with Sinfonieorchester Liechtenstein and the Großes Festspielhaus Salzburg with the Zagreb Philharmonic Orchestra. In 2026, Runtz led Sinfonieorchester Liechtenstein on tour in Poland as part of the 30th Ludwig van Beethoven Easter Festival, appearing with violinist Arabella Steinbacher in Warsaw, Kraków, and beyond. Upcoming engagements include a collaboration with Lang Lang and the Zagreb Philharmonic, at Vaduz Classic with Nadine Sierra, Javier Camarena, and Sinfonieorchester Liechtenstein, and his symphonic debut in Italy with Orchestra Sinfonica di Milano.
Runtz’s 2025 Vienna debut with Sinfonieorchester Liechtenstein drew exceptional notice. Reviewing the ensemble’s first appearance at the Wiener Konzerthaus, Pizzicato wrote that Runtz led Scheherazade in a style “as assured and clearly defined as it was elegant, inspiring the orchestra to a magnificent achievement.” His work with the Zagreb Philharmonic Orchestra has likewise become one of the defining artistic partnerships of his career. Since assuming the role of Chief Conductor in 2021, Runtz has led the orchestra in a wide range of repertoire, from the central symphonic canon to Croatian masterworks, major international appearances, and ambitious recording projects.
Runtz’s artistic partnerships include an increasingly prominent roster of international soloists, including Lang Lang, Frank Peter Zimmermann, Fazıl Say, Camille Thomas, Arabella Steinbacher, Michael Barenboim, Roman Simović, Radovan Vlatković, and Vivi Vassileva. From 2017 to 2024, he served as Principal Conductor of the Polish Royal Opera in Warsaw, where he continues to collaborate through selected productions, maintaining a close relationship with the Polish operatic landscape while expanding his symphonic profile across Europe and beyond.
