Szun Waves brings together Norfolk-based electronica artist Luke Abbott; drummer Laurence Pike, of Australian electronic jazz trio Triosk; and saxophonist Jack Wyllie of Mercury-nominated UK group Portico Quartet. New Hymn To Freedom is their second release and it's an album to lose yourself in. Across six live improvisations the trio create psychedelic nebulas of sound ambient expanses scribbled with plaintive sax melodies and carried along by drumbeats that pad and thrash, as Abbott's synths wobble and fizz and shimmer and fly like streamers. Sometimes these tracks evoke the Buchla synth experiments of Suzanne Ciani. The trio also reference UK producer Four Tet and Alice Coltrane, whose influence can perhaps be heard in some of the harmonies, which have an Indian classical flavour. The haunting, 12-minute title-track, which closes the album, is especially engrossing. It builds from a sparse opening, layering drones, warped overtones and shrill soprano sax and gradually rampingup the tension before melting away. It leaves you wanting more.
