Founded by Małgorzata Krej, the choir performs with distinguished musicians Andrzej Perkman (piano and arrangements),  Wojciech Pulcyn (double bass), and Krzysztof Szmańda (percussion). It specialises in Polish music for children by composers  such as Edward Pałłasz, Witold Lutosławski, Romuald Twardowski, Adam Skorupka, and Barbara Kolago, setting texts by  Jan Brzechwa, Julian Tuwim, Władysław Broniewski, and Dorota  Gellner. Its repertoire also includes numerous traditional songs.  For Krej, a cofounder of the Warsaw Village Band, those songs are  an essential part of introducing the youngest children to music.
