Sounds of the crucifixion of Jesus Christ and his final moments on the Earth gleaned from the works of the Gospels will reverberate through the air during a Holy Week concert in Demorest. The Piedmont College Chorale and Orchestra will perform two works by 19th century Belgian composer César Franck at 7:30 p.m. Tuesday in the Piedmont Chapel. Admission is $10 for adults, $5 for students and seniors, and free for Piedmont students, faculty and staff.
