Concert Hall, Costa Mesa, CA- At over 8,000 square feet, the ribbons of the Acoustical Canopies were gilded in aluminum leaf. Floating high above the stage they are an integral part of the acoustical design of this space. At the rear of the stage is the “Tracker” pipe organ which we gilded for C.B. Fisk . All in all, the Pipe Organ and the acoustical panels totaled almost 11,000 square feet.
