The Warsaw Boys Choir was founded in 1990 at the Warsaw Music Academy upon the suggestion of the Academy Professor Andrzej Chorosiński. Krzysztof Kusiel-Moroz, lecturer and assistant at the Department of Choral Conducting, was the founder, artistic director and the choirmaster. The Choir is composed of boys aged between eight and fourteen, all attending Warsaw primary schools. In 1998 a men's choir was founded, an integral part of the entire Choir composed of secondary school boys who had recently left the boys' choir. The Warsaw Boys' and Men's Choir give between thirty and forty concerts a year, both in Poland and abroad. The extensive repertoire ranges from Gregorian Chant to the contemporary, with performances of music by Polish composers, while recordings include music from Pergolesi, Schubert and Mendelssohn to Penderecki and George Crumb.
