The Holographic Ear (2007)

Mn is sleeping in bed. The sun is rising on another apparently normal day, outside the birds are singing. He begins to stir, there's something odd about the birdsong - sounding more like a complex musical composition it gradually builds in intensity, as it reaches a crescendo Mn wakes up with a start. Thus begins a journey of transformation in which Mn is subjected to a series of extraordinary encounters that force him to confront the nature of reality and perception.
