Thanks to the vision and generosity of Lillian Disney, the Disney family, and many other individual and corporate donors, the LA Phil moved into Walt Disney Concert Hall in 2003. Designed by Frank O. Gehry and Associates, the building is internationally recognized as an architectural landmark and one of the most acoustically sophisticated concert halls in the world. From the stainless steel curves of its striking exterior to the state-of-the-art acoustics of the hardwood-paneled main auditorium, the 3.6-acre complex embodies the unique energy and creative spirit of the city of Los Angeles and its orchestra. Los Angeles enjoys music by the LA Phil, the Los Angeles Master Chorale and visiting artists and orchestras from around the world. The LA Phil performed its first concert on October 23, 2003.
