The way ruminating thoughts leave trails deeply embedded into your brain from repetition is a deeply apt metaphor for “Circle Trails” from the Swedish ambient pop artist Stainwasher. Ethereal vocals float over chorus heavy synth lines and a plodding beat that seem to ratchet up the inherent tension here of obsessive thoughts exposed and laid bare. Fans of artists like A Sunny Day in Glasgow and Grimes will find a lot to sink their teeth into here.
