“The Music Center at 50 is a mature performing arts center. Its newest venue, Frank Gehry’s celebrated Walt Disney Concert Hall — already an L.A. icon — turns 12 in the fall. Next year, the Museum of Contemporary Art’s Arata Isozaki building reaches its third decade. The Broad museum is almost finished. All this can be found concentrated within three blocks, clearly positioning Grand Avenue as one of the country’s most important arts destinations.”
