Up C Down C is a brilliant post-rock band out of the UK. Their name is quite ridiculous, (properly Up-C Down-C Left-C Right-C ABC + Start,) but their sound is epic "instrumental rock to wake the devil." Think Explosions In the Sky as done by The Sword, and you're in the right ballpark.
The band reportedly spent four years working on this new album, Embers, and whatever hard work that was spent creating it wasn't done in vain. Lyrics are never missed and they don't waste too much time getting to the point. There may be millions of post-rock bands out there to choose from, but this is one I think you should pay attention to.
