Organist Steven Ball of Atlantic City, New Jersey, stands in front of the Kotzschmar Organ on Friday at Portland’s Merrill Auditorium. Ball was part the Historic Organ Tour, a group of about a dozen organists from around the country who visited eight U.S. and Canadian cities in 11 days, including Bangor and Portland. Portland was chosen as the finale because of its famed, two-of-a-kind organ. Staff photos by Ben McCanna
