Bästard - Radiant, Discharged, Crossed-Off (1996)
If you like Slint, Three Mile Pilot, or Enablers, make sure you listen to this. Vocals occasionally appear, but this album spends most of it's time experimenting with instrumental post-rock textures. I can't recommend this enough, just give it a shot b/c IT'S REALLY GOOD.
Let there be post-rock.
