LA’s new Disney Hall got through its opening weekend of three concerts in great style, writes Joshua Kosman. “Taken in tandem with Thursday’s opener, the evenings added up to a beguiling snapshot of musical life in the Southland – venturesome, swaggering and ready to embrace whatever cultural developments may be passing through. In addition to its own extravagant charms, at once noble and puppyish, Disney Hall reveals anew the strength and resilience that this orchestra has attained under Salonen’s leadership.”
