WBEZ and 312 Presents host a private concert with Black Prairie tonight for High Fidelity members -- and we've got two tickets to give away.

Email contests@gapersblock.com with your name, phone number and "Black Prairie" in the subject line by 4pm; we'll choose an entry at random. The station's doors open at 6pm on Navy Pier; see the map here. Show starts at 7pm. UPDATE: Congratulations to our winner, Darlene L.!
