Last night I saw Radiolab @ BAM. The show, “In the Dark,” was really good. There was a mix of dance, creative visuals, and pre-recorded interviews that blended into a very fun night. During the show, the audience was asked to participate by holding an LED light with a battery. I’m not sure how many people participated, I can tell you it was an impressive sight. Imagine 300 or 400 mini-lights glowing in the darkness of a theater. It felt great.
