From September to May, the symphony orchestra performs a range of classic and modern works. A fall/winter Pops series features accessible classics as well as Broadway show tunes and light opera. Most performances are held at the Long Center, but a few of the Pops concerts are held at the Palmer Events Center, 900 Barton Springs Rd. (512/404-4500). The orchestra’s administration operates out of Symphony Square, a complex comprising an outdoor amphitheater and four historic structures from the 1870s. Narrow Waller Creek runs between the seats and the stage of the amphitheater.
