Confluence features Balkan dances by Marko Tajčević interspersed with contemporary tangos by Ray Granlund. After many years of performing these works in recitals, the husband-and-wife duo of violinist Zachary Carrettin and Mina Gajić wanted to record them—not as two separate sets but as a confluence of dance-inspired music influenced by two distinct regions and cultures. They chose to travel back and forth between duo and solo, interweaving Balkan dances and tango nuevo in the way the pair has done in live performances.
