Based on this success, the Flex Ensemble has appeared at venues such as the Concertgebouw Amsterdam, the Alte Oper Frankfurt, the Beijing Performing Arts Center, the Meistersingerhalle Nürnberg and Festivals such as the Festival de Musique de Menton, the Sommerliche Musiktage Hitzacker, the Heidelberger Frühling, and the Prishtina International Music Festival. On many occasions their performances have been recorded and broadcast live on German Radio (SWR and NDR Kultur) and Dutch Radio (Radio 4).
The Flex Ensemble’s dedication to the major piano quartet literature is complemented by their wish to enrich artists and audiences alike by commissioning new works. Their programs include world premieres Márton Illés, Gérard Pesson and Johannes Schöllhorn. They collaborate with a wide range of distinguished artists such as Wolfgang Güttler (double bass), Oliver Wille (violin), Albrecht Mayer (Oboe), Daniel Rowland (violin), Elsbeth Moser (Bayan) and Kostas Raptis (bandoneon).
