Honestly, I've been rather nonplussed with progressive, instrumental, post-rock bands of late. Somehow the noodling, epic experimentations have started to sound too familiar... Obstacles cured me of this sad state by completely blowing my mind. These guys know how to construct some ridiculously complex and surprising tunes. This is their most recent release (I think, but their releases seem out of order) and it is incredible. The EP is name-your-price, but if you feel like it you can shell out a few bucks for their full length (which a massive slab of experimental awesome).
