I've been waiting for a long time to find maybeshewill's "In Amber" in Soundcloud! The opening track of their latest album Fair Youth is my personal favourite composition of the record (read the review here).
The piano / drum combination is probably the foundation of this particular song. Somehow the guitars feel more of a support/ambient instrument, at least that's the way I feel after more than 50 listens. If you enjoy this, seriously listen to the full album in the review. One of the best post-rock things last year!
