The sun rises in Haydn's music: The audience of classic.Esterhazy enjoys it every time anew. In the case of his String Quartet op. 76/4, the upward gesture of the first violin even literally led to the nickname "The Sunrise". The Isidore String Quartet's star is also on the rise: founded in 2019 in New York at the Juilliard School and named after Isidore Cohen, the great American chamber musician and member of the Juilliard String Quartet and the Beaux Arts Trio, the multi-award-winning ensemble has set itself the task of approaching the familiar repertoire as if it were new and the new as if it had long been established. It is fitting that jazz pianist and composer Billy Childs has now written a new work for the Isidore String Quartet, his fourth string quartet. And together with the young Italian pianist Martina Consonni, a master student of Sir András Schiff, the four will also perform Schumann's Piano Quartet op. 44: the sounding document of a happy time, "full of power and freshness", as Schumann's wife Clara enthused, "extremely brilliant and full of effect".
