"Raw Atmosphere" marks not only C01's first EP for iq140, but also his artist debut. The first in his "Unreal Atmosphere" series, the release includes three minimally-composed tracks that feature beautiful filtered pads and synths. "Indivisible" has a melodic hook and resonant toms, backed by reverberated strings. Next is "Onion Eyes," featuring a distorted bell in the lead with metallic and crunchy drums and flourishes. Finally, the release closes with "The Raindrop Postlude," which builds upon syncopated waves with a slicing sawtooth stab, bringing in a whistle towards the end to complete the effect.
