Astari String Quartet

The Astari String Quartet is a dynamic ensemble of passionate musicians dedicated to exploring new styles and pushing the boundaries of classical music. Anna Popil and Louis Greiner play the violin, Lucas Aerts the viola, and Urszula Markowska the cello. Founded in Belgium around a shared vision of creativity and curiosity, the quartet brings a fresh voice to the rich tradition of chamber music through its bold, contemporary approach.
Since the beginning of the 2025–2026 artistic season, Astari has been a member of the Netherlands String Quartet Academy (NSKA) in Utrecht, a prestigious institution dedicated to mentoring and developing chamber music ensembles. In January 2026, Astari joined Le Dimore del Quartetto, an international cultural network that supports young professional string quartets by organizing residencies and concerts in historic houses and villas throughout Europe.
The quartet is a Brand Ambassador for Jargar Strings and collaborates with the brand to develop its distinctive sound.
The quartet has already established a solid foundation for its international profile. In 2025, it participated in the prestigious ProQuartet Festival in France. This formative experience gave the musicians an opportunity to further develop their ensemble sound while becoming part of a vibrant international community of string quartets.
Astari also participated in the Rurhoff Masterclass, where the ensemble studied with all four members of the Quatuor Danel. The quartet also performed in concerts as part of the Ostbelgien Festival.
