Paul DeMarinis has an amazing piece in the show.

Firebirds, which uses propane gas flames, which are fed with high voltage electric currents, which then creates a magnetic flame allowing for the flames to act as a speaker. In the instillation four such flames are arrayed all in cages that resemble oversized pet-bird cages. Each of the four goes off at diffrent times, each playing a speach by Rosevelt, Hitler, Stalin, & Churchill respectivly. The affect of exprencing this piece, especially in a city who's history is so tied up with the second world war, is quite intense. Not to mention that the specticle of it, arrayed in a large open hallway, filling the space with fire and sound.
