The Walt Disney Opera House built by Frank Gehry in Los Angeles in 2003 highlights his signature contemporary style of sweeping metallic surfaces. The interior features one concert hall with excellent acoustic qualities due to its spatial and material qualities.
Day B: Downtown LA. Walt Disney Concert Hall, Dorothy Chandler pavilion, Grand Park, and Lady of our Angels Cathedral are all nearby within walking distance and interesting to see them all (111 S Grand Ave Los Angeles, CA 90012)
