There's always Wacken! I have a friend that visited Europe for a month earlier this year (he's Polish) and he stayed in Prague. I think 7/10 concerts he went to he had to travel to Germany for the shows. He did see Taake and Kampfar in Prague though!
The other player couldn't make it to the show. Hoest mentions it at some point here, I'll give the time stamp when I get there Edit: actually I think the video skips that part
