I guess it’s the Fringe, or the Festival itself that brings these guys here, but this particular busker is well worth a look at. Today he was in Manner’s Mall. I could hear him a block or so away & the sound he was producing made me wonder if one of the theremins was in use somewhere close. But no he’s doing it with a violin, what looks like some satanic tuning fork, and a whole lot of other odds & ends. And he speaks into a mike too.
