I accidentally stumbled upon a link to the following YouTube videos. They tell the story of the first experiments in electronic music in the UK and how it later on became EMS (Electronic Music Studio), the creators of the VCS3 and the Synthi 100.
I really enjoyed watching these videos. Just seeing how these guys started out. It must have been very frustrating having all these ideas and only crude technology to make it a reality.
