Pavel, Joseph, Patrick and Emery Cardas began playing professionally in 1985 in Italy, where the four brothers grew up musically. Following concerts in Italy and a successful tour in Colombia, they pursued their advanced studies at the Musik Hochschule in Vienna and subsequently with the world-renowned faculty of Indiana University, particularly under the guidance of Rostislav Dubinsky, founder of the Borodin Quartet and violinist of the Borodin Trio.
