I just dug up
this 5 minute video (estimated) by Nate Harrison on the history of the
Roland TB-303. If you've followed its history there's nothing too
new, but he expertly lays out the headspace the music world was in at
the time, and how it was (mis)used through the ages. For anyone
who jumped into techno lore late in the game (yeah okay, it's all relative)
this is a great watch to backfill details on where the sound came from.
