More music like the OST from speed grapher?

Finished the speed grapher anime, it’s pretty damn awesome, but the music is great! I love it, specifically these songs. I like the higher pitched sort of organ I guess it would be, or more electronic piano sounding thing. Anyways, do you know any more songs like this?

Shutter Speed

couldn’t find the others on youtube, so here is the 4shared links i uploaded, you should be able to play them directly.

Battle II (my favourite one)
Ruined town (second favourite)
