In the three years that separate the first edition of Colors from this sequel, tech-house dons Circulation seem to have honed their sound into an even more breathy and streamlined affair. Merging their stripped-down, quietly muscular techno with a meandering, druggy ambience, the duo of Paul Davis and Matt Jackson have created a document that veers between '80s nostalgia, Jarre-esque journeys and edgy escapism. At times, intricate Detroit techno is taken to quietly sublime levels via a forceful primordial pump, but there's plenty of standard (i.e. mediocre) dancefloor stuff here. With each track representing a different color, this is definitely one for the synaesthetics.
