The chamber music ensemble Oxalys has been founded in 1993. Its repertoire ranges from Haydn to contemporary music, with a strong focus on the belle epoque era (1860-1930). From its inception onwards, having started at the Brussels Conservatory, the ensemble's instrumentation – a string quintet, the flute, the clarinet and the harp – has hardly changed at all.
Oxalys has performed on stages and festivals in Belgium and abroad, including at Concertgebouw Amsterdam (NL), Beethoven Haus (DE), Auditorio Nacional de Música (ES) and Saint Petersburg Philharmonia (RU), and at festivals in Granada (ES), Rheingau and Schleswig-Holstein (DE). The ensemble's discography comprises works by Mozart, Strauss, the French Impressionists and Mahler. The ensemble has collaborated with soloists such as mezzo-soprano Christianne Stotijn, baritone Dietrich Henschel, tenor Christophe Prégardien and soprano Claire Lefilliâtre.
