What I heard, was that it was mastered for LP format, but label being little cautious if engineer made is little bit too "soft" in fear of vinyl not being able to handle all the high-pressure all-at-max digital frequencies. Not sure if finally ending up sending "less mastered" audio.
Judging the length of tracks, it's clear 2xLP would require edits to make sound idea. No sense to have 3 or 9 minutes on one side while 25+ on the other. I'd assume material needs to be cut to even parts over the sides, despite it will change original track length. I think that hardly matters. I'd rather take edit with 15 min per side, 60 mins in total, that cut "as is" from CD lengths, track per side.
CD:
1 Part 1 9:23
2 Part 2 25:06
3 Part 3 21:00
4 Part 4 2:55
But in other hand... some material simply benefits from being CD and I'm happy to keep listening original CD. Release is good for those who prefer vinyl and crave some actually GOOD MERZBOW to be available.
