was founded in January 1992 as a vocal quartet (Halina Pribula, Beata Brzóska, Leszek Kalina - the artistic director and founder, Lech Gattnar) and as an art-independent ensemble of the Polish singers` union Collegium Canticorum. Its goal was to commemorate the forgotten work of Jiří Třanovský (1592-1637). After giving out the record for the Těšín Museum, the Radio Ostrava and after several concerts the singers have decided to continue their existence in the field of the Renaissance a`capella choral music. They also attached some new members (Kateřina Kafková, Aleksandra Sładeczek, Grażyna Sucha, Roman Najder, Radek Duda).

They had a little break from June 1998 to November 2002. Concurrent reactivation connected with Polish art union ARS MUSICA changed the vocal background from the mixed to male choir with countertenor voices.

The "Company" has already given some concerts for the Polish and Czech TV and for the local radio-station in Ostrava. It is a member of the Choral and Musical Organization in the region Zaolzie, the Polish Union of Choirs and Orchestras in Warsaw and the Union of Czech Choirs in Prague.
