What I find interesting about this track is the fact that it's got all these elements to lure our attention... Although there is this Ambient mood about it which allows it to slip into the background whilst remaining mesmerizing.
It was definitely the airy pads and the deep pianos which created a moody atmosphere. The drums and the bass keeps us moving with their compelling bounce, especially when the percussion arrives. I don't know what "Vergangenheit" means, I'm pretty it's got something to do with nostalgia though since that seems to be the theme of the track sonically.
