Then some metal.
With COLD SUN SILENCE, my starting point was Paradise Lost / Amorphis-sort of stuff. You know, that melodic guitar hovering over power chord mass.
(Maybe there’s more of the latter, with it’s folksy & grim feel)
And yes, the lead guitars go in thirds, like those boys in Thin Lizzy & Iron Maiden used to do. Although in this kind of heavier context, they sound more “hetfieldistic”.
Small chunk of winter.
