It was actually a small mistake on my part. When I synced the 1977 mix, I noticed that there were a few places where the wav file had inverted phase compared to the earlier analog laser discs and the 1985 mix. In order for the few patches from the analog mix to work correctly, I had to correct the inverted phase in some spots. I accidentally included the phase corrected versions of side 1 and side 2 instead of the straight LD rip. I'm planning on fixing this in V2 of the torrent, though the gout synced track will have the correct phase.
