Faun is a Munich based Medieval “Paganfolk” group. They just released an album after 4 years. I admit the only song I’ve heard is the first song that they released ahead of the album. That is this song.
This is “Spieglein, Spieglein” by Faun. That means “Mirror, Mirror.” It is from the album they just released yesterday, November 15, titled, Marchen & Mythen, which is “Fairytales & Myths” in English.
I would normally include a link to a translation of the lyrics, but it seems no one has published one. If that ever happens I will update this post.
