I had a laugh reading this thread after my first listen because I too got the weird Neverending Story vibes from Diamond Jigsaw.
Really enjoying the album. I haven't really been paying attention to the earlier incarnations of these tracks that most of the forum seems to have heard, so it all pretty much sounds fresh to me. "Bird 1" has been in my head all day, I love it. I love soft-and-reflective Underworld, so Louisiana is almost an instant favourite for me. Beautiful track.
The main one that falls flat for me is "Hamburg Hotel" for reasons already mentioned - what we do hear sounds great, it just doesn't really seem to go anywhere so it ultimately feels unsatisfying.
Looking forward to getting the limited edition in the post soon..
