In a relatively short period of time the choir accomplished outstanding results in the interpretation of bulgarian choir pieces, with an extraordinarily comprehensive repertoire including authentic folk songs from different regions of Bulgaria, polyphonic arrangements, original work based on folk motives and incorporating avant-guard means of expression (including aleatoric and sonoristic), Old Church Slavonic songs and others.

A number of choir pieces by the following composers were written and dedicated to the Academic Folk Choir: Ivan Spasov ("Marinko Moe Doshtryu", "Vido, Vido", "Hortsa I Pripevki ot Pirina"); Nikolai Stoikov ("Mari, Nazlun Vakla Todoro", Dva Madrigala", "Razboliala se Dragana" and "Malka Moma Dvori Mete"); Assen Diamandiev ("Da Sam Studena Voda"); Petar Krumov (two songs from the East Balkan region, "Na Lazar", "Na Sryata", "Lazarska Pesen") and others. The Academic Folk Choir was the first to perform these pieces and thus became the initiating force of the New Folk Wave, which was later taken up by other bulgarian folk choirs.

The choir performed very successfully in Bulgaria and abroad (Belgium, Switzerland, Germany, Italy, Russia, Finland, Poland, Turkey, etc.). The choir was highly praised for its performances and international festivals (Bodgosh Musical Impressions - Poland, Gurtenfestival - Switzerland, the International Festival of Chamber Music - Bulgaria, the New Bulgarian Music Festivals and other forums). The choir has produced television specials, a compact disc, long-play records, audio tapes, studio recordings in the National bulgarian radio.

The commentaries of the foreign musical critics reviewing the performances of the choir noted its unique and authentic singing style, its great mastery and exciting renditions of the material. It was said to uncover a whole new world of mastery of the Bulgarian voices, creating something beyond our image of the Bulgarian folk song, enchanting with the beauty, precision, artistic freedom, and stable intonation.
