Boettcher Concert Hall, located in Denver, Colorado, was the first symphony hall in the round in the United States. Built in 1978 by Hardy Holzman Pfeiffer Associates, as a home for the Denver Symphony Orchestra, the hall is part of the Denver Performing Arts Complex, the second largest performing arts complex in the United States next to Lincoln Center in New York.
Boettcher originally opened to mixed reviews. Due to its size in relation to the size of the community it serves, its 2,362 seats are often not completely filled. Tuned acoustically with a full house in mind, Boettcher originally suffered from hot and cold spots when the theater was only partially filled.
In 1993, the theater underwent a major acoustical renovation. The height of the seat backs was adjusted, additional acoustic reflectors were added, and acoustic curtains were installed which allow the theater to be tuned for specific performances--even during a performance.Boettcher is home to the Colorado Symphony Orchestra. The Colorado Symphony Music Director is currently Andrew Litton.
