Back catalogue: Leftfield

Review: With a title inspired by the utterances of The Oracle of Delphi, a cult of female priestesses who reportedly "changed the course of civilisation" by inhaling volcanic vapours, it's clear that Lee Burtucci and Olivia Block's first collaborative album is rooted in paganistic visions and experimental mysticism. It's comprised of two lengthy tracks, each accompanied by edited 'excerpts', and combines Burtucci's experimental synth sounds and tape loops with Block's processed vocalisations and hazy field recordings. Dark and suspenseful, with each extended composition delivering a mixture of mind-mangling electronics, creepy ambience and musical elements doused in trippy effects, it sits somewhere between the charred "illbient" of DJ Spooky and the deep space soundscapes of the late Pete Namlook.

Review: Calling the curtain on Field Records' Waterworks trilogy, Yui Onodera turns his ear to confluences of hydrology and history, dedicating his latest record to Japan's Kiso Three Rivers and their transformation by 19th-century Dutch engineering. The Kiso, Nagara and Ibi rivers, once prone to catastrophic flooding, were reshaped under the guidance of Johannes de Rijke, whose work helped protect Nagoya from seasonal deluge by 1912. Onodera, known for his nuanced sound architecture, approaches this subject with a finely honed ear for subtlety, layering quiet field recordings with fuller instrumentation, evoking the widening of a river from brook to strait. The A-side's bell tones provide a sensory-meridian intimacy, processed alongside guitar, and ethereal pads; while the B-side's contradictorily colossal quietude makes itself across two long-form studies, which drift through sampled water and restrained electronics.
