Quadratum is North Georgia’s premiere and only auditioned ensemble focused on the advancement of music. Membership is by audition and consistent demonstration of physical and psychical rigor. Its levels are Novice, Apprentice, Adept, and Elders; those wishing to join are eligible to audition after the passing of the applicant’s eighth birth anniversary. This fundraiser concert opportunity provides the friendly experiencer access into its world of authentic Ghanaian drumming (albeit performed by, largely, gringos); 16th century polyphony (performed by 21st-century humans); and new musics from living composers (performed by authentic living musicians). Directed by surrealist Brian Parks and stoic Catherine Moulton, this secretive musical cabal invites you to one night of mystery, caprice, and ludic adventure! Plus concessions are available in the lobby.
