I have one extra ticket to the Emerson Quartet's concert on February 5th at Bing. The ticket is B-level seating, which normally costs $15 + service fee (which is $2-5 depending on whether or not you're a student), but I'm selling it just for $15.

In case you're wondering, I'm only selling it because I received another ticket via a class that I'm taking right now. All premium, A-level, and B-level seating is sold out.
