Seattle’s new performance venue, Marion Oliver McCaw Hall comprises 75% new construction and 25% renovation. Home to the Seattle Opera and Pacific Northwest Ballet, the new hall had it’s operatic debut on Saturday with a performance of Wagner’s “Parsifal.” As with all concert hall renovations, it took a real performance to truly put the new acoustics to the test. In the opinion of the N.Y. Times’ Critic’s Notebook, this one is a winner with thanks to Jaffe Holden Acoustics (who, by the way, are next to my CT hometown).
