A light glows from a crowded tent. Bodies move in unison as a DJ’s head bounces up and down with the beat. And you hear – nothing?

Such is the Silent Disco, most recently staged at Tennessee’s Bonnaroo 2008 Music Festival, as seen on CDM’s events.noisepages.com. See Jason’s blog post, photos, and look at the whole festival in photos.

The trick was to provide wireless headphones, thus making a dance party for the iPod age. The result is certainly surreal, as you can see in video (watch about halfway in).

But I think the event doesn’t go far enough. How about a truly silent disco – no headphones, no sound whatsoever. Naturally, there should still be a DJ. (What are those guys really doing, anyway?) Dancers would have to synchronize on their own beat, a la the creepy hypnotic power of the “IT” in A Wrinkle in Time. (Google it.) Of course, this would be even more fantastic if you could do it at a festival, get a whole bunch of people in on the joke, and then confuse the hell out of everyone else.

Any takers? (Or maybe it’s been done before?)
