Here is that documentary I mentioned in my post @ammonite/breaking-through-sand-sculpture. I was unsure should I post it as I don't own the rights for the music that is used but it was made for promotional purposes of the organiser and was never made for broadcast.
I can't find out how to refuse rewards on Dtube so any rewards this gets I will split 50/50 with the musicians if they ever join Steem or Dtube.
