The Maine Edge spoke with Dennis Cox, professor of music and director of the Choral Music Program at the University of Maine, about the University Singers’ spring tour. Over spring break, the group performed free public concerts in Maine, New Hampshire and Massachusetts. Cox, who plans to retire at the end of the school year, directs the group. “This group right now is as good as any I’ve had. I’ve been with the Singers for almost 36 years, and it has been amazing,” Cox said.
