Great list! Didn't know about Sexual Purity. Know personally the people from first 3 bands though :)
Btw, Old Cat's Drama guitar Divuar is guitar / male vocalist in Zwyntar.
ΠΠ°Π΄ΡΠΈΠ»Ρ recently made an album where he re-recorded their stuff in Ukrainian. Bandcamp
DK Energetyk post punk band that recently went fairly popular, their tracks also were added to Stalker 2.
Zagreb, Sudno, BaWN, SMURNO - haven't seen these folks live but their recordings are great.
Edit1: Dark Folk band Folkulaka absolutely needs to be in the list.
