"50 years ago this month an engineer named Bob Moog presented his new invention at the Audio Engineering Society Convention: handmade 'voltage-controlled electronic music modules' that allowed a performer to create sounds by patching the modules together and adjusting knobs. He started taking orders (and made a new friend at AES, Wendy Carlos), and the rest is, literally, a part of musical history.
Today we’re at #AES2014, stewarding a piece of our shared cultural history and celebrating 50 years of a total revolution in music. Photo: Bob Moog at AES 1964"
