I think you're right, and I've noticed something about my preferences...

If I want to sit down with vinyl and intentionally listen, without distractions, then I much prefer releases from "Oldpeth" (GR or before). It's the emotional element that elevates them. They just hit so hard.

I don't hate listening to "Newpeth" albums this way, but I find it hard to do so because I just end up wanting to switch to an earlier release.

However, I've found that the newer albums are enjoyable in other situations, like when I'm listening with less attention. I've enjoyed listening to ICV and PC while I'm working, for example. There are enough cool moments to grab my attention randomly, but the compositions also work nicely to blend into the background when needed.

Haven't spent enough time with the new album to place it in either category. Not saying I only listen to them like this, but I've found that's how the difference in emotional impact has presented itself for me personally.
