I heard a Folk rock/metal song and i can't find it again.?

I heard this song on youtube and in the beginning it has a fiddle and maybe someone humming but it sounds like irishy if that makes sense. The video had the album and the album had the band standing in front of a tree i believe. I remember a tree though. But the song went from like fiddle and humming to like metal but it kept the same kind of tone with the fiddle and all that. Please help before i go crazy trying to find it.
