This track was inspired by travelling to and around London Underground (on the Circle Line) then getting off on a South Bank station and walking by the Thames to Tate Modern listening to the waves and finding peace amongst the noise and chaos of London. A rift, or gap, in the circles of busyness if you like.
As I was in London for Tangerine Dream's farewell tour perhaps, in a small way, this track is kind of inspired by them.
