I've been enjoying Tripper from Danish post-rock outfit Efterklang quite a lot lately. It's got a bit more vocals on it than I usually care for, but as is the case with Sigur Ros, they're a bit whimsical and in a language that means nothing to me, so really the net result is they're a bit more like a another instrument than anything.

From what I can tell from their blog, it looks like they're recording a new record now. Definitely looking forward to that!
