The Walt Disney Concert Hall at 111 South Grand Avenue in Downtown Los Angeles, California is the fourth hall of the Los Angeles Music Center. Bounded by Hope Street, Grand Avenue, 1st and 2nd Streets, it seats 2,265 people and serves (among other purposes) as the home of the Los Angeles Philharmonic orchestra and the Los Angeles Master Chorale.

Lillian Disney made an initial gift in 1987 to build a performance venue as a gift to the people of Los Angeles and a tribute to Walt Disney’s devotion to the arts and the city. The Frank Gehry-designed building opened on October 23 2003. Both the architecture by Frank Gehry and the acoustics of the concert hall (designed by Yasuhisa Toyota) were praised in contrast to its predecessor, the Dorothy Chandler Pavilion.

After the construction, modifications were made to the Founders Room exterior; while most of the building’s exterior was designed with stainless steel given a matte finish, the Founders Room and Children’s Amphitheater were designed with highly polished mirror-like panels. The reflective qualities of the surface were amplified by the concave sections of the Founders Room walls. Some residents of the neighboring condominiums suffered glare caused by sunlight that was reflected off these surfaces and concentrated in a manner similar to a parabolic mirror. The resulting heat made some rooms of nearby condominiums unbearably warm, caused the air-conditioning costs of these residents to skyrocket and created hot spots on adjacent sidewalks of as much as 60 ºC (140 ºF). After complaints from neighboring buildings and residents, the owners asked Gehry Partners to come up with a solution. Their response was a computer analysis of the building’s surfaces identifying the offending panels. In 2005 these were dulled by lightly sanding the panels to eliminate unwanted glare.
