The vocoder had a turbulent history with Japan. In 1945, it was used to encrypt tactical conversations concerning the deployment of the atomic bomb in Hiroshima. In 1980, Yellow Magic Orchestra (YMO) used it to cover the Archie Drell soul standard "Tighten Up." The Japanese-manufactured Roland SVC Vocoder was widely used by Bambaataa and the hip-hop old school and then ultimately the Beastie Boys, when they suited up for this Ultraman-inspired Kaiju Eiga wrestling match.
