I also love Agalloch, it's a shame they split last year, but I won't lie, I wasn't a fan of the Serpent and the Sphere.
Their first three albums were a huge part of my College years, I still listen to their albums without boredom, love them.
To be hot be honest I recently downloaded an audiobook app to my phone because I drive all over for work and am in my truck a lot, and right now I am half way through the book Journey to the Center of the Earth. What a great story. Been loving every second of it so far.
