He graduated in composition (1981) after studies with Bronisław Kazimierz Przybylski and in music theory (also 1981) from the State Higher School of Music in Łódź.

For six years, he conducted the Academic Choir of the Łódź Polytechnic, then for 2 years - the Grammar School Mixed Choir in Łódź. With choral ensembles, he made archive recordings for the Polish Radio Broadcasting Station in Łódź, including works by such composers from Łódź as Andrzej Hundziak and Karol Mroszczyk. He also conducted many concerts, e.g. in Łódź, Glasgow and Edinburgh.
