Can’t say much about ‘Marbles’. But ‘Nåke Du Finn I Skogen’ is quite reminiscent of Lacrimosa, the symphonic-goth-rock band — especially the man’s vocal is like Tilo Wolff himself participating on the track. Check out e.g. ‘Alleine Zu Zweit’ (the video is moderately NSFW) and ‘Kabinett Der Sinne’. Not very folky, though.

You might also dig Camerata Mediolanense, since you’re familiar with neofolk.

Let me know if any of these tickle your fancy, I’ve got more vaguely in this vein.

Also, Lindy Fay Hella and the vocalist Kristian Espedal were both in Wardruna, which might be relevant.
