"Lights" is the first track: sonar-like bleeps, groovy percussive elements, round kicks and an hypnotic arrangement with subtle changes.
"Arcade" is more rhythm-fuelled, based around drum elements that weave in and out of the structure, moving from left to right. A construction tool.
The second track on the B side is "Echoes", which has a more mental approach. A slow build-up starting from filtered beats, delayed digital drums, assorted percussion layers and a lot of FX workout on another complex mixing tool.[info from label]
