Full of melancholy-frosted electronics and emotive swells of classical piano, the new single from Nordic duo Ólafur Arnalds and Janus Rasmussen is a delicate, icy slowburn - much like the project itself. Kiasmos is a collaboration that's taken seven years to properly flower, launched in 2007 to early acclaim but derailed again and again by other projects: Rasmussen is the Faroe Islands-born talisman of cult crew Bloodgroup while Arnalds' solo piano compositions have seen him hailed as one of the biggest contemporary classical talents around, increasingly borrowed by Hollywood for blockbusters like 2012's the Hunger Games. 'Burnt' proves good things come to those who wait, though - a brute, beautiful Jon Hopkins-ish classical-electronic crossover that sounds like a rave-up in the lonely burrows of a misty glacier. The pair's self-titled debut lands on October 27 via the ever-reliable Erased Tapes. On this evidence, it should be a wintry treasure. Check it out below.
