Formed in 2009 by four inner-space travellers from western Finland, Kairon; IRSE! is a rare bird, near-impossible to classify. The Wire describes their music as a "viperous cocktail of space rock, Greg Lake-era King Crimson and free jazz", and ever since their debut album, 'Ujubasajuba' set Bandcamp buzzing in 2014, their records have been hidden classics of modern psych-rock for those in the know. Their third album 'Polysomn' is a treasure-trove of glitching, elated sounds, that takes psychedelia into a new dimension. 'Polysomn' brings to mind the melodic lightning of bands like Dungen, the chainsawing alternative guitar fuzz of My Bloody Valentine, the sparkle and dreamscape of Slowdive, and the technological envelope-pushing of Radiohead's outsider works.
