There’s an ineffable sense of mystery to this collection of previously unreleased material from saxophonist John Surman and jazz vocalist Karin Krog. Recorded over three days in 2013, abandoned when the theatre project it was commissioned for never came to fruition, and finally unearthed this month by Trunk Records, Electric Element sees the duo (along with Surman’s son Ben) abandon traditional jazz entirely in favour of a set of wonderfully weird vocal and electronic experiments.

Over nine tracks – five substantial compositions and four brief interstitials, which mainly act as codas to the longer pieces – Surman shirks his sax in favour of wind synth, bass and contrabass clarinet, plus various effects units. Krog, for her part, shrieks, growls, mutters, and occasionally speaks.
