You've heard of Don Buchla and Dave Smith. You may even have heard of a fellow named Bob -- but there are many others whose work on electronics, physics, and music led to the amazing electronic instruments we enjoy today. From Raymond Scott to Harald Bode, from Hugh LeCaine to George Philbrick, we'll explore hidden connections in the history of synthesizers and audio electronics, and meet pioneers whom you may never have heard of, but whose work is essential to modern music-making.
