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.

Just got back from Burning Man a few days ago but check out all the photos I was able to shoot.
