I'm not a huge Agalloch fan, although I enjoy their style of progressive folky post/black metal.
And The White EP was really the thing that got me most, even though it has very little to no metal on it.
This piece is so bloody sad sounding, and I have always had this weird feeling about it, The White EP and Friday afternoons.
So Melancholy and beautiful.
Also The Wickerman samples and Christopher Lee add a lot to the mood/vibe/atmosphere of it.
The Whole EP I love, but this is by far the piece that I take the most from.
