Even after a couple of albums, the instrumental combo known as Szun Waves still sounds unknowable. British producer Luke Abbott’s synthesisers have a dreamlike quality, and Australian drummer Laurence Pike (Triosk, PVT) conveys the immediacy of a live jazz room, with Londoner Jack Wyllie’s saxophone hovering in mysterious, melodic spaces between. That strangely organic mix, wholly improvised, is everywhere on New Hymn to Freedom: the whirring, whooshing feedback squalls of “Fall Into Water”, the noisy, interactive tumult of “High Szun”, the loose swing feel and soprano sax chants of “Temple”, and the lonesome synth meditation of “Moon Runes”. On the longest piece, the closing title track, the trio explore blurred zones between jazz and experimental electronic music, easing gradually into tempo from the primordial haze.
