Orange County’s new Segerstrom concert hall at the Orange County Performing Arts Center is working out the kinks in its acoustics. But the hall has some challenges, not the least of which is attracting audiences. At performances by two of the world’s great orchestras – the New York Philharmonic and the Kirov – there were plenty of empty seats. “When that happens, something is wrong. And what is wrong is that prices are too high (a $200 top for the Kirov) and that there is not enough culturally curious elite in Orange County to support an elite showplace.”
