Within the language of machines.
Uninfringed by human emotions.
Kraftwerk - Kakteen, Wüste, Sonne (1971)
Old, unseen, and with a title that translates to "Cacti, Desert, Sun", "Kakteen, Wüste, Sonne" was originally recorded for the german tv show Beat Club in 1971, but as it appears it didn't make it on the air until April 19th 2009. I.e. yesterday.
