Four troubadours met on their musical journeys, and became friends. Starting from their own traditions and compositions, passing through ethnic music, they look for a common language. Eastern violin, South American rhythms and songs from the North flow into each other along bird-free improvisations. The Birds of Passage are Danish-Kurdish singer Luna Ersahin, violinist Shalan Alhamwy from Syria, French-Venezuelan guitarist Ray Riveros and Jonas Malfliet from Belgium on accordion.
