Mark Swed likes the new $200 million hall on first encounter. “I like the way it feels. The light and airy interior is hospitable, the silver organ pipes (the instrument itself is still a year away from installation) intriguing. Architect Cesar Pelli’s undulating glass exterior has a welcome, outdoorsy transparency. I like the firm, upright seats. I like the way I imagine Segerstrom will sound once it finds its bearings.”
