As construction finished in the spring of 2003, the Philharmonic postponed its grand opening until the fall and used the summer to let the orchestra and Master Chorale adjust to the new hall. Performers and critics agreed that it was well worth this extra time taken by the time the hall opened to the public. During the summer rehearsals a few hundred VIPs were invited to sit in including donors, board members and journalists. Writing about these rehearsals, Los Angeles Times music critic Mark Swed wrote the following account.
The walls and ceiling of the hall are finished with Douglas-fir while the floor is finished with oak. Columbia Showcase & Cabinet Co. Inc., based in Sun Valley, CA, produced all of the ceiling panels, wall panels and architectural woodwork for the main auditorium and lobbies. The Hall's reverberation time is approximately 2.2 seconds unoccupied and 2.0 seconds occupied.
Toyota says that he had never experienced such an acoustical difference between a first and second rehearsal in any of the halls he designed in his native Japan. Salonen could hardly believe his ears. To his amazement, he discovered that there were wrong notes in the printed parts of the Ravel that sit on the players' stands. The orchestra has owned these scores for decades, but in the Chandler no conductor had ever heard the inner details well enough to notice the errors.
