Robert Henke had this to say about the creative process involved in making the album:
' The title of this album, Ghosts, came to my mind at a quite early stage. I liked it due of the large field of associations it provokes. I started taking notes about topics connected to the term, read about mythologies and collected ideas. I also often write fragmentary texts, short cinematic scenes that I come up with when my head is idling and I have time to kill. One of these texts is included in the artwork of the CD and the vinyl edition and it is an essential part of the Ghosts album, it serves as a window to a bigger drama, and the music offers another view. The text also links the Ghosts album to the Silence album from 2009. Both stories are related, I just don't know yet how. Independently of the aim to create a new album I constantly try out things in the studio, and some day in December 2010 a structure started to emerge that had a dark and evil quality. I knew this would become a core part of a future album and I gave that sketch the working title 'Ghosts'. Finding new material with similar color turned out to be more difficult than I did anticipate so I changed my strategy and worked on sounds and shapes of very different vibe; whimsical little sonic creatures, potentially mean or helpful spirits that have their very own life. I recorded and transformed sounds from objects I found in my flat; glasses, paper, thin plastic sheets, stones, pebbles in a salad bowl and so on. I believe I became a pretty good foley artist by doing so. The track 'Taku' mainly consists of recordings I made with two empty glasses clicking at each other, and 'Unstable Matter' is an exercise in applying complex transformations to all kinds of recordings: a bunch of vintage cymbals, my own voice, metal plates, singing bowls, bells, and a rusty hi-hat. During the entire year 2011 I composed a lot of sketches, mainly rhythmical tracks, but most of them I had to throw away at some point. Either I did not like specific elements in them or they did not fit in my theme of a world of ghosts. Very often I assigned the same title to numerous different tracks in that process, since I did like the title and the message it potentially could convey but not the music assigned to it. 'Foreign Object' is the most extreme case here; a track with that name got completely discarded on the evening prior to the final CD mastering process and replaced by a new composition created in a rush at that very night: During the creation process of the album I spent a lot of time trying out different orders of tracks, order is important to me, I aim to create a work of art that works as one large structure, not just an arbitrary collection of songs. Even whilst, or maybe even because this is not the way most music is consumed in the age of random mp3 collections. '
