Growing up on the north Atlantic island of Iceland bestows one with an unusual and often intense relationship with light and colour: Summers come with endless days, Winters with scant sunlight yet increased sightings of the Aurora Borealis; the mysterious and awe-inspiring glow across the sky. Channelling these energies, Exos comes to Tresor with his Green Light EP, a five-track collection of the sort of spectrally rich techno synonymous with the Northman’s 27-year career. Across the EP, the five tracks fizz and pulsate driving ever forward, making the release’s title a three-way play on words referencing the continuous travelling of photons, the verdant warping of the Northern Lights, and the universal colour for Go, for forward propulsion. Smart wordplay can also be found in titles like Grátt Silfur, a term in Íslenska (literally “grey sliver”) which signifies a tension between two parties, further extending the colour metaphor and dark/light dichotomy found elsewhere. The digital release comes with three extra tracks that continue the dynamic energy, pushed along by the same shifting, mutating force where the music often feels like voices calling out from the darkness or the shimmer of light as the sun rises across the horizon. Green Light EP continues this year’s blazing return from an artist who, similar to his output, is never stagnant: ever changing form yet ever moving forward.
