The Agora Theatre and Ballroom in Cleveland, OH is an architectural marvel and one of the most revered live entertainment venues in the U.S. Midwest. A year after acquiring the operating rights to the storied space, concert giant AEG Presents unveiled the results of a sweeping $3 million overhaul that, in addition to restorative work on some of its stunning interior architecture, included a brand-new audio system from Adamson Systems Engineering for the 2,100-capacity Agora Theatre.
