Chamber vocal group "B-folk" is a formation for Bulgarian folklore. The name reflects the duality of the repertoire - both classic folk songs and songs in which two types of folklore are present - e.g. Bulgarian is combined with Spanish, American or folklore of other nationalities. The repertoire consists mainly of author's music, song processing and arrangements of popular folk songs by the conductor, maestro Svetoslav Baltakov, and his aspiration is to enrich the repertoire and to attract young people to folklore singing.
