YCAT's Fibonacci Quartet is the first ensemble ever to win both First Prize and the Audience Prize at the 2024 Premio Paolo Borciani. They tour Germany this summer with recitals taking in Aschaffenburg, Pfungstadt, Wolfegg, Würzburg's Mozartfest, and the Rheingau Musik Festival. Their programmes pair the classical poise of Haydn and Mozart with the fire of Bartók and Janáček and the romanticism of Schumann. Manage Cookie Preferences
