In my ears, it is heavier and stronger, at times makes me think of older Mania with heavy sub-bass level rumble and scrap metal. But that's not all what there is. Four pieces, 40 mins, variation of things.
Umpio CD is new 2022 finished, but using old unreleased album session together with new stuff. So you got hints of the old broken-junk Umpio, as well as modular electronics, and result is very tasty. Advanced but also crude and in-your-face harsh noise.
All reissues are "as is". Audio is not mastered at all compared to former CD's. If you want louder, you turn volume knob louder. Great dynamics found in all Macronympha items. Barely ever brick-wall kind of thing, despite being NOISE.
