Apologies to those of you who've already heard and seen this.
The link below leads to an academically presented, but extremely well
informed film about the 'famous' Roland electronic musical instrument.
Mostly it contains stuff which many will already know, but I doubt that
the history, ethos and culture which the 303 engenders, has been as
comprehensively documented on film before.
You'll need Quicktime (which is free to download).
I need to acknowledge that I saw this first on the Discogs music tech
forum.
Enjoy.
