Jacek Ostaszewski was born in Kraków in 1944 in an artistic family. His father was a sculptor and a stage designer, and his mother an actor. In the Sixties, he appeared on the Polish jazz scene as a double bassist, playing with the most outstanding musicians of the times: Komeda, Trzaskowski, Kurylewicz, Stańko, and Makowicz. In 1970, he formed “Osjan” – an acoustic music group. This group, pioneers of New Age music, toured all over Europe. “Osjan” has released six vinyl albums and four compact discs. The group’s concerts, during which Ostaszewski plays recorders, are highly popular both in Poland and abroad. During the 80s, he broadened his compositional palette by writing music for the theatre. He has composed for around 80 productions (including 15 for works directed by Krystian Lupa), and ballet music arose out of his collaboration with Boston’s Beth Soll Dance Company. He has also written the music for three feature films, ten shorts, and four television plays. His own holistic method of musical training – “The Path of Sound, The Path of Silence” – and his workshops are popular both in theatrical circles (he lectures at Kraków’s State Theatre School) and among music therapists, psychologists, psychiatrists, and educationalists (he has ongoing collaborations with the Polish Milton H Erickson Institute and the Cultural Promotion Centre). Besides numerous workshops in Poland, he has also led intensive courses in the U.S.A., Japan and Portugal. His characteristic flute playing may be heard on Zbigniew Preisner’s film music, including Krzysztof Kieślowski's "Three Colours - Blue", in which Ostaszewski also appears on screen in a cameo role. He has also made his directorial debut (Ionesco’s “The Chairs” at the Teatr Współczesny (Contemporary Theatre) in Szczecin).
