Alan Rich isn’t ready to make prognostications on what an orchestra will sound like in LA’s new Disney Hall, but he’s impressed with how it looks this far into construction. “The hall itself — the ‘Ralphs/Food 4 Less Auditorium,’ it will say in modest lettering on the door handles — is close enough to completion that you can sense the intimacy of the place as compared to the Chandler Pavilion. It’s not only a matter of smaller size; it’s the contour of the room that seems to wrap itself around you.”
