Folk elements on Lunar Strain

a whole acoustic folk album , or jesper would do one, with oscar of hammerfall, since they played together before and also Jesper co wrote half the tracks on Renegade and Im curious to see what it would sound like, because i never got to hear ceremonail oath.
 
You should check out Suidakra. Plenty of folky bits in there. A good starting point might be Emprise to Avalon, which has an awesome acoustic instrumental towards the end that you'd probably love. Amazing band.
