A bit of background on this album:
Field recording played a huge role in it. The album is meant to be a journey from start to finish with some piano pieces interweaving the narrative. The field recordings were done with binaural microphones.
The result is that the recordings sound 3D when you listen back wearing headphones, the sounds are very localised and immersive. A lot of the designed sounds came from random places, there's a huge mix of binaural recordings, contact microphone recordings, and recordings from under water using hydrophones. Many of the recordings were taken at Cockatoo
