In the opening track of this single, Geiger builds up from a simple beat into increasingly active loop layers, with slow-surf tone-fades providing the most distinctive touches to the otherwise fairly stock techno, though the fairly slow pace also helps give it character.  Things fade to a quiet close, and “Bum Bum” picks up with another basic beat, though snapping flourishes on the end pick it up somewhat.  The other notable features are some gasps and bent tones, the latter of which gain volume and prominence of the course of the song before again fading down into the exit.  Some nice moments, but nothing too special.
