Osias Wilenski was born in Buenos Aires, Argentina. From an early age he studied piano with Professor Vicente Scaramuzza and harmony, counterpoint and composition with Dr. Erwin Leuchter, who had been a pupil of Alban Berg. From Leuchter comes his early interest in 12-tone music, a system that Wilenski has abandoned since. During the 1950s and through the suggestion of pianist Arturo Rubinstein, Wilenski won a scholarship to study at the Juilliard School of Music in New York, where he resided for several years. There he studied composition with William Bergsma, William Schuman and Vincent Persichetti. He also had private piano lessons from virtuoso Simon Barere, of which he was the only pupil. He started a solo pianist career and played concerts in New York in Hunter College and Town Hall.
Czech violinist and producer Vít Muzík (b. 1972) is one of the most multifaceted musicians working on the contemporary classical music scene. His abilities both as a performer on the concert stage and in the recording booth have led to appearances on more than 60 recordings in the Navona and Ravello catalogs, making him one of PARMA Recordings' most frequent collaborators.
