[smazibummigue]

Anything from:
Mono
Tortoise (avoid "The Brave and the Bold" as it is not instrumental)
Helios
Red Sparowes
Godspeed You Black Emperor!
Jaga Jazzist
Tristeza
Windmills by the Ocean
Pelican
Triosk
Murcof
Four tet
Max Richter
Boards of Canada
Electric Birds
This Binary Universe

That should be a start to (newer) instrumental music.
