Natural Snow Buildings

There are two audio files in my archive of this set. One is a lossless FLAC rip (Sheffield.flac) from the Live Sheffield & London 2012 tape released on Blackest Bootlegs, recorded by Ben Nash. The other file (Sheffield_alt.mp3) is probably another tape rip? Better quality rip but transcoded to a lossy format. Both obtained from Soulseek. The full Blackest Bootleg tape rip on YouTube is also linked. This set is the first part of the video. The print used as the cover image was made for this specific live set by Jake Blanchard of Tor Press. The sample used at around 19 minutes in is the same sample used in God's Fossil, but other than that it sounds quite different from that track?
