A little more than a year after its Pittsburgh show, experimental orchestra HiTEC -- short for "The Histrionic Thought Experiment Cooperative" -- will perform again, and likely for the last time. Just don't expect a reprise of what you experienced before: the event is described as an "uncert" or "uncertainty concert." The project is the brainchild of Pittsburgh-based artist tENTATIVELY, a CONVENIENCE.

Just exactly what it is and how it works takes a bit of explaining -- fortunately, Manny Theiner did just that in a feature story about HiTEC's 2009 performance. Footage from that show, at The New Hazlett Theater, can be seen here.

The performance will take place at 8 p.m., Sat., March 13 at Carnegie Mellon University's Kresge Hall. The suggested donation is $6 (CMU students free).
