PORTLAND -— Christmas at the Cathedral will offer an opportunity for calm reflection of the joys of the holiday season. The concert emphasizes the sound of trumpets and brass from the Portland Brass Quintet, and the organ played by Dan Moore.

The Choral Art Singers will present a new work by Charles Kaufmann, “A Longfellow Winter.” The Choral Art Society commissioned this piece from Kaufmann, an award-winning composer and founding director of The Longfellow Chorus.

Christmas at the Cathedral is scheduled for 8 p.m., Saturday, Dec. 5, with a noon preview; and at 2:30 and 7 p.m., Sunday, Dec. 6.

Tickets range from $10 (preview show, available at the door only) to $30 with a limited number of $5 youth tickets, and will be available through the Choral Art Society by calling 828-0043 or visiting www.choralart.org.
