I can highly recommend Negura Bunget. Start with " 'n crugu bradului", one of my all time fave albums. Was lucky enough to catch them live last year. Awesome experience.
As for Austrian bands, you should all check out Pungent Stench.

Seen pungent stench live, theyre pretty cool.

Poland does have a huge scene, but sorry I can't think of many bands to add.

Anyone heard of Rakoth? They are odd, lol.
