I'm Romanian. For me, the best metal band here is Dordeduh (and also my favourite band ever), it's Experimental Black Metal, they are awesome. You can listen to their side project band as well, Sunset in the 12th House, it's more like an Ambiental Post-Metal. They are good too. And you can try Drudkh (from Ukraine). And then there are plenty of bands you can discover even from YouTube suggestions.

I wanted to add three videos to this post, but not permitted.
Check out some other songs, such as "Run" and "Enter the Asylum" on youtube.
I hope somebody enjoys them!
