Instant art, with music, or vice versa.

Had a wander round the Edinburgh Art Fair at the Cornmarket.    Nothing within our price range caught our eye so were leaving without even taking the camera out of my pocket.   However, just at that moment a strange sound emerged from an adjacent hall where we discovered this weird happening.
Music from a base guitar and the female voice of an ex "Rezillo", all accompanying an artist working on glass in turn projected on to the wall.
Music was labeled "Shamanic".  It had a certain resonance with both of us.  Why?  I can't help but wonder.
