Never heard of any of these before so I had to do a little research.
Neutral Milk Hotel: Nice acoustic/folk sound to it. A solid 9.
Finntroll: Can’t say I’ve ever heard a folkmetal band before. I enjoyed it, though. I’ll give them an 8
Punch Brothers: I think I found a new favorite. Fantastic folk band. Love the instrumentation. 10 all the way.
Overall rating: 9
But that’s just me, music taste isn’t really something that can be measured haha
