They say about it:
Whenever you turn a Spieluhr (aka music box), you are surprised how fine, pure and present the sound of it is. The only pity is that the sound is so short and does not resonate any longer. So we set out to build a Soileuhr sound that sustains longer. We grabbed some different Spieluhren and processed them heavily vigorously. We layered, freezed and even stretched them like we could. The result is a Klang instrument full of grace - one part clouds and one part Spieleuhr. Check it out and have fun.
