Four established chamber and solo musicians joined together and developed into Balkan Quartet- a dynamic and inspiring string group. Serbian violinists Sinisa Ciric, Mirna Ogrizovic, violist Danijela Zezelj-Gualdi and Bulgarian cellist Martin Gueorguiev started their collaborations as section leaders of the Gwinnett Ballet Orchestra in Atlanta, Georgia, often playing as a representative quartet for this organization. Their collaborative playing portrays an energy and musical understanding that comes from their mutual background.

Balkan Quartet plays music by talented contemporary composers: Nickitas Demos, Aleksandra Vrebalov (winner of the American Academy of Arts and Letters Charles Ives Fellowship, 2007), Brian Mitchell, Aleksandar Gajic, Milos Simic, Zvonimir Tot, and Konstantin Blagojevic, and merges it with classical string quartet repertoire by composers Martinu and Glasunov. Their focus is to involve and inspire composers to create new music that would use an indigenous Balkan language, reviving the rich Balkan folk heritage on a high artistic level.

Balkan Quartet has performed significantly around South East, having their important appearance at the Piccolo Spoleto Festival (Spotlight Concert Series) in June 2008, Charleston SC. In April 2009 they were invited to represent Serbian Embassy at the cultural event “Passport to DC" in Washington DC. In September 2009 they performed at Kennedy Center, Millennium Stage in Washington DC. Their performances have been broadcasted on NPR (91.7FM, Georgia Public Radio, “Afternoon Concert") and live streaming from Kennedy Center.

Balkan Quartet is Quartet in Residence at the Georgia Perimeter College.
