St. Olaf Choir in town - concert sold out

The highly esteemed St. Olaf Choir will give a concert at Trinity Episcopal Cathedral. According to the choir's national tour web site, the concert is sold out. However, I have heard that you might be able to purchase tickets at the door. The cost per ticket is $35 - although it might be a little higher since they weren't purchased ahead of time.
The choir's famous conductor, Anton Armstrong, will direct all of the pieces. Here's where you can find the program. Note that Armstrong works with choirs at the Oregon Bach Festival every summer, so if you miss this program (or are impressed with Armstrong), you might try to catch him in Eugene this summer.
