The college has put on an annual Christmas concert since 1927, which remains a tradition of the local community. From its inception, it has featured the music department's choirs and orchestra. In 1940, Christianson began working with painter Cyrus M. Running to incorporate murals with the concert to reflect the music's themes. Running completed the designs until 1978, when their development was taken over by David J. Hetland, whose murals have traditionally extended 56-by-20 feet. After Hetland's 2006 death, mural designs were taken over by artist Paul Johnson. The concert is currently performed four times annually on Concordia's campus and twice annually at Orchestra Hall. Over 450 students perform for an audience of twenty thousand, and the concert is broadcast on radio and television. The 2009 concert, "Journey to Bethlehem", was recorded by Twin Cities Public Television and won a regional Emmy. It was broadcast nationally by members of the Public Broadcasting Service.
