More than half a century has gone by since Over-the-Rhine hosted Saengerfest, but it’s back again. A German-American choral tradition first held in Cincinnati in 1849, Saengerfest attracted thousands of people to the area to witness the festive holiday choral celebrations. What was once an integral part of Cincinnati holiday tradition faded away with the popularity of May Festival, but the tradition is back, in line with Cincinnati’s thriving vocal arts atmosphere still buzzing after the World Choir Games. Come hear the best choirs in the area singing in Over-the-Rhine’s historic churches for one weekend only. 6-10 p.m. Friday; 5-9 p.m. Saturday. $15 per day in advance, $20 on-site. Various locations in Over-the-Rhine. christmassaengerfest.com.
