Students at Tennessee School for the Blind received a memorable experience this week when they performed in the acoustically rich confines of the Volcano Room at Cumberland Caverns. Twelve students with the choir and six students with the jazz band played for an audience that included members of the Warren County Lions Club, an organization devoted to eyesight preservation. “I can distinguish the cave formations, although I can’t see exact details,” said Candi Herrera, a visually impaired student from Oak Ridge.
