Don Buchla demonstrated a CV control FM radio to David Tudor and John 
Cage in the early 60's:

"Cage and Tudor visited me at my studio in Berkeley. ...My studio at 
that time was ten feet wide and I worked out on the sidewalk.  It was so 
crowded in there we hauled the workbench out on the sidewalk on good 
days and set up my oscilloscope and worked out there.  Cage came by and 
for voltage control I had hooked up my keyboard to an FM module that I'd 
built, a little module that was an FM receiver and I could play stations 
on it because I had one of the first varactor tuned FMs.  Cage, as you 
can imagine was, just enormously interested in the fact that I could 
tune each key to a station and then proceeded to play the radio."
