1860s Magic Concert

Charles Wheatstone, developer of the Wheatstone Bridge,   conducted a ‘Telephonic Concert’ at the Royal Polytechnic Institution in London. The band played two stories down, the sound from their instruments being inaudibly transmitted (through vibration of steel wires) up to the concert hall. Harps then sounded out the scores, much to the amazement of the audience. No electricity was used for this, it's just a posh version of two cans and a string.
