From 1967 to 1971, the building was extensively renovated. While the basic architecture of the building remained unchanged, the entrance was moved outwards and faced with a -high arched window. The one-ton chandeliers were rebuilt and their crystals replaced. The original polychrome decor was replaced by a brilliant white and gold design. Ornamental elements in the auditorium were replaced by acoustical baffles to convert the former movie theater into a lively sounding concert hall. The back of the building was extended, adding almost to the stage, and making space for dressing rooms, a music library, and rehearsal rooms.
