it's 4 long all-instrumental slabs of doomy instrumental ultra-heaviness, and it can be listened to in it's entirety here. I just bought it for 5 bucks. I like this bandcamp thing, they take paypal. Convenient.
Good stuff - I enjoyed that. I've actually been looking for some instrumental doom lately as I find it good to work to. Vocals can sometimes distract my thought process, but I love the doom atmosphere when doing some types of work.
Any other recommendations for instrumental doom? I know of Sunn O))) and they are great for certain moods, though I'd love to hear of more that are a bit less minimalist (like Bongripper).
