BRW should have been unofficially added to archive.org in 2004, right around the time it was added to Etree, furthurnet and BTaT. No shows were uploaded to archive.org since there was nothing on Etree or Furthur to mirror at that time. I believe I dropped the ball on that one way back when, I was more concerned with trying to rehome all the Phil Lesh shows when thephilzone.etree.org had to go offline.
