There he began to study music, which has been the main passion of his life. But it took him a while to get entirely into it. He returned to Israel as a young man, where, he says, his first love was killed in a terrorist attack, and he joined the Israeli army as a way to "channel my anger." From there, he took a corporate marketing job in Amsterdam, where he started playing folk music on an acoustic guitar. "I met Jim Croce and played him three songs," Dagan says. "One he really liked and wanted to record. Then he died six weeks later." Nevertheless, Croce's support got Dagan to take his music seriously. He began to travel between the folk clubs in Amsterdam, Paris, and Brussels.
