Love the chugging strat rhythms, love the crystal clarity of the mix. I also really like the many different rhythms that come and go. It certainly evolves.
I think there's a pop/click at :15 when a layer of some kind comes in.
OMD is a nice reference, they had some cool stuff for sure.
the Bandcamp version just kind of ends abruptly, which might be entirely intentional given your motivation for the piece, I think I get it. Very sorry for your loss.
thanks for sharing your excellent music.
