Chill song with looping background vocals "go insane"
 

Hi, I'm looking for the name of a song that I've heard previously and randomly got stuck in my head.

It's in the techno/trance/psychedelic/chill genre with slow, heavy synth. I would describe it as close to XXYYXX's style.

There's a frequent loop of a distorted female voice saying "go insane" or something similar. Then it switches to a high-pitched melody or something.

If it rings any bells, let me know!
