The Bangor Daily News reported two music professors at the University of Maine — Ludlow Hallman and Dennis Cox — will retire at the end of the semester, and the upcoming Bangor Symphony Orchestra concert will be their last time working with the UMaine vocal groups they’ve led for decades. Hallman has conducted the Oratorio Society since he began teaching at UMaine in 1970, and Cox has led the University Singers for more than 30 years. Hallman said the two have been through a lot together and have become “very good friends.” Both men spoke highly of UMaine’s music program, facilities and students. “We have great students right now, and I mean that sincerely,” said Cox. “It’s always about the students. It’s always the most rewarding part of any day,” added Hallman.
