Ha, I witnessed this happening several months back here in Gainesville, FL a few times by I believe the same person.
It was always dark and I never was right by the guy so I couldn’t tell he was air bowing that violin but this is what he was doing. I saw the police stop the guy from busking at least once too.
What’s wild is how LOUD the guy was with his portable rig in busy parking lots. He never was in normal foot traffic/busking areas.
From what I've seen it looks like they like suburban shopping areas. In most of the videos they are in the parking lot of a Marshalls, TJ Maxx, or Target.
