Oskar Sala - Zeilgalerie in Frankfurt, 1993

From christian moeller’s website, Sala, a pioneer of electronic music played his Trautonium, an early electronic musical instrument invented in Berlin in 1930. For this live performance, his concert was displayed as a gigantic video projection above the urban flow. The metal façade of the Zeilgalerie was turned into a giant TV screen in the public space.
