The Blind Orchestra plays live, with a conductor on the extreme right

When a group of people make live improvisational music together, there are a lot of visual clues they send out on stage to keep the harmony intact. For instance, a trumpeter can simply turn to the guitarist as a signal for the latter to begin a solo. Or, the bassist can give the drummer a nod indicating that it's time for the two of them to step up and start a jam. Of course, if there is a conductor controlling the proceedings, then he or she uses an array of intricate hand and head movements to give structure to a composition. But what if all the musicians are playing blindfolded? What if it's only the conductor who has the luxury of sight? It's a totally different ball game then, as the audience at a performance by Blind Orchestra will find out.
