Here is their video for Sink Into the Sin, though I highly recommend listening to the tracks Slowsnow or Viridian.
Sad melodic electronic noises supplemented with disturbing Polish male and female vocals. Very beautiful with a hint of trauma, perfect beats and key changes but with lingering suspense and samples of real instruments.
