Like Halfslaap (released on a 3-inch by Standard Form in 2010), Halfslaap II is a very restrained, meditative piece with a slow and subtle development that seems to play tricks with the notion of time. The hypnotic quality of Halfslaap II comes from two simple violin phrases with are almost identical, but different in length, causing them to overlap at different points each time. In the course of 35 minutes, these floating violin tones are pulling the listener into some sort of dreamstate. The violin on Halfslaap II is played by Anne Bakker, with whom Rutger worked before on the pieces Koploop (2007) and Fabriek Bakker Fabriek (2008).
Stiltetonen (album version) is a continuation of sound piece that was composed to play continuously in a small alley in Amsterdam. As part of the project Tussen-ruimte ('Between Space'), the looped, minimalistic piano melody transformed the space to an oasis of comtemplative rest in the midst of the busy city center. With it's spatious pace, the sounds of the city became an integral part of the composition. For this album version, the piano loop forms the base for a more set composition, complimented with extra layers of audio to create an equally immersive home listening experience.
