Sound of history

Via OddityCentral comes this most remarkable thing. The people above are listening to the sounds of their city, Dresden, during World War 2. Developed by Markus Kison, the sound is not produced by speakers, it does not make its way through the air but is transmitted through metal. Placing your elbows on the railing and palms over your ears will bring the sound to you.

I can only imagine this to be surreal but deeply moving. To hear the past superimposed over the present.
