Other bands I didn't mention, (that deserve a mention
):
Mono: Sad that I missed their tour this lasy year. Definitely one to check out, though it's easy to mistake them with the British Duo 'Mono'. Though the duo's hit Life In Mono would be a good track to listen to anyway.
Moving Mountains: Reminds me a lot of A Silver Mt. Zion. Though heavier in some parts, though doesn't really verge on post-metal.
Pram: Blends with Dream Pop, and thus, they use lyrics in their songs. They sound almost Jazzy or Mathy at some points. However, defiitely give them a go.
Tortoise: Not to everyones liking. They use a strange mix of post-rock, electronica, and minimalism IMO. Some great soundscapes, that have a nice groove to them.
This Will Destroy You: I always mix up these guys with Do make Say Think for no logical reason. I don't have their albums, only a few tracks. However, from the soundscapes, each song seems to work well in isolation.
