An Octave Above, one of the hottest a cappella vocal groups in Chicago, features eight professional singers who combine their vocal talent with a love of a cappella harmonies. The group of four men and four women will perform holiday favorites along with doo wop, jazz and pop standards. Fine Arts patrons may remember An Octave Above from their crowd-pleasing performance in 2010.  Admission to the concert is free of charge, although donations are gladly welcomed. A special holiday reception with the artists follows the concert, hosted by the Fine Arts Committee. Bring the family!
