Students in the School of Music, Theatre and Dance are putting on a haunted performance on the top floor of the Lurie Tower on North Campus. The tower will be decorated for Halloween and the students will be dressed in costume, playing eerie music on the 53-bell, 43-ton Charles Baird carillon. A carillon is the instrument typically at the top of towers, consisting of at least 23 cup-shaped bells. At this Halloween-themed event, the students have practiced spooky music to be played.
