Album: Solace (LP 2006)
Jakob are often hailed as one of the best, if not the best, active band in post-rock, and for good reason. Although they are entirely instrumental, they eschew the stereotypical twinkly crescendo-ridden output of more well-known acts like Explosions in the Sky or Mono, instead opting for a contemplative, sometimes heavy, and simultaneously bleak and hopeful approach to an increasingly stale genre. It's hard to describe through words, so I'd just recommend that you listen to Malachite, one of their best songs.
Also, their production is nothing short of Godly.
