Here a link to a BBC series about Electronic Music.
I know some of you will love it.
The Roland TR808 is also mentioned at some point.
You will need to create a account with your email to listen to the programme, I think the programme will stay up for about a month.
You will hear Electronic sounds from the 50s up right up till the early 80s.
The programme starts with a Theremin an acoustic piano. The Theremin can sound very much like a distortion pedal.
