Reid Willis (Check out the album The Longing Device) This guy is probably the closest, plus modern classical elements.

More must listens by him: Sow the Silt, Draining the Blade, Personal Orbit, Home in the Void, Overflow

Max Cooper (Check out Aleph2 [seizure warning for the video])

To a lesser extent (not as dark):

Flying Lotus

Amon Tobin (Dust for a Duster)

Robot Koch

Tycho - Adrift (I don't like a lot of his music, but this one is a banger)

I will edit this comment and add more, because I know more will come to mind.

Also you can look up the genres IDM and Dark Ambient in general.
