Pareidolia is the ability humans have to recocgnise patterns in places where they should not be. It's what makes us recognise faces in unpainted wood and what makes clouds look like anything we can imagine.
This piece is based on this effect but the how it comes out in sound and music. I looked for patterns in sounds around me to see if I could find material to base a composition on.
