The choral activities at Ljubljana Conservatory of Music and Ballet started progressing after composer and conductor Ambrož Čopi assumed leadership of the choir in 2010 , knowing how important and fulfilling it is for young musicians to sing in a choir, to discover the beauty of vocal music and the joy of singing together with others, feeling the energy and power of choral art and getting inspired for future work.
After four years of growing quality and various achivements at competitions: first place at International choral festival Samoborsko zborsko protuletje (Croatia, 2011), first place in mixed choirs and chamber choirs categories at International choral festival in Gdansk (Poland, 2012), Grand prix at Festival of contemporary music Canti veris Praga (Czech Republic, 2013), first place at National competition of children’s and youth choirs Zagorje ob Savi (Slovenia, 2012), second place at International Choral competition ''Gallus'' Maribor (Slovenia, 2013), third place at International Choral competition Montreux (Swizerland, 2014), the decision was made to split the choir into two groups - one choir consists of all the students of the conservatory not included in school orchestras, the other choir (Chamber choir) consists of about 40 singers who are willing to improve their vocal technique, to sing a more difficult range of choral music and reach higher performing standards.
Choral activities at Conservatory of Music and Ballet Ljubljana (Slovenia) started progressing when composer and conductor Ambrož Čopi assumed leadership of the choir in 2010. After four years of growing quality and various achivements at competitions, the decision to split the choir into two groups was made - one choir that consists of all the students of the conservatory that are not included in the schools' orchestras, and the other - Chamber choir - that consists of about 40 singers who are willing to improve their vocal technique, to sing a more demanding range of choral music and to reach higher performing standards. During the past three years, conductors' assistants were Petra Jerič, Tine Bec, Evgen Bibianko, Tom Varl and Lara Willewaldt. Chamber choir regulary collaborates with vocal educators Edita Garčević Koželj and Tatjana Vasle. The KGBL Chamber choir, embraces a wide range of music genres and styles, from the Renaissance to modern music. In the past three years the choir had commissioned many prominent composers, such as Lojze Lebič, Tadeja Vulc, Damijan Močnik, Črt Sojar-Voglar, Peter Šavli, Andrej Makor, Tine Bec, Matej Kastelic to create new compositions, which the choir successfully promotes at concerts and competitions in Slovenia and abroad.
The last three years have been very prolific for the KGBL Chamer Choir, as it achieved second and third place at the International Choral competition Talinn (Estonia, 2015); won the Grand prix in Moscow (Russia, 2016); it achieved first place at the National Choral competition ''Naša pesem'' (Our song), Maribor (Slovenia, 2016); second place at the International Choral competition ''Gallus'' Maribor (Slovenia, 2017); first place in category Polifonia and second place in category Folklore at the International Choral competition in Tolosa (Spain, 2017) and first place at the International Choral competition in Cork (Irland, 2019) .

The conductor's idea to make synergy between a new generation of young singers, composers and conductors became true. In collaboration with Slovenian music publisher Astrum new compositions by Slovenian composers are successfully promoted. After three years the Chamber Choir KGBL has become one of the most prominent Slovenian choirs.
