Free A Capella Rock Concert Tuesday Night

With movies like "Pitch Perfect" and television shows like the "The Sing-Off" the art of a cappella has become increasingly popular amongst music fans of all ages. 

This Tuesday, Oct. 22, the Green Hills Public Library, 8611 W 103rd St., will be hosting a free concert from Ac.Rock. The a cappella group performs classic rock songs from the '50s on down. 

Starting at 7 p.m., the hour-long concert combines tight vocal harmonies with "freewheeling humor". While it is free, you do have to register in advance online.
