You wax faux-nostalgic about the heyday of early robo-Kraut-rock, your early signed pressing of Radio-Activity is rivaled only by your original Neu! Super / Neuschnee 7-inch, and you got a belly laugh at that one scene about the record the nihilists once cut in The Big Lebowski. Kraftwerk fans, today is your lucky day. The original one-of-a-kind prototype vocoder Kraftwerk pictured on the rear cover art of and used to record "Ananas Symphonie" and "Kristallo" on their 1973 release Ralf & Florian. As of the time of this writing it's already up to five grand, so if you want yourself an extremely expensive piece of history for electronics and electronic music, you'd better get a move on, schnell.
