Kronolith (instrumental)

The guy behind Irgalom, The Arbiter, Zsoloszma, Abandoned Mortuary, The Exit Wound, and others has a relatively new project called Kronolith.  I'm not sure how to categorize it beyond "instrumental" but it's pretty easy to listen to and great background music if you need to focus on a task.  I've been really enjoying it!  He's released two albums:

Volatile State (piano)

Solid State ("amped up" version with guitars and whatnot of Volatile State)
https://abran.bandcamp.com/album/solid-state

I Absolutely LOVE instrumentals!

I listen to them daily in my personal life as well as at work with the clients I am privileged to work with.
