Prolific Norwegian trumpeter and ECM veteran Arve Henriksen returns with Estonian guitarist/composer Robert Jürjendal in tow, matching his idiosyncratic shakuhachi-style melodic condensations with Jürjendal's glassy electro-acoustic soundscapes and sonorous percussion.

Henriksen releases a lot but is remarkably reliable; his playing is so versatile that hearing it dematerialise into different ensembles and individual methodologies is always a treat. Jürjendal is a veteran guitarist, but doesn't approach his instrument from a purely classical standpoint, taking a Fripp-inspired path towards texture, processing and looping his sounds until they're barely recognisable. The duo share a similar love for Hassell's Fourth World ambience, and here inject new life into that mood.

Jürjendal's percussion is impressive: he offsets cascades of oddly-tuned electronics on 'Tuonela' with booming, ritualistic tom hits that punctuate Henriksen's melancholy phrases; and on the brilliant 'Ancient Bells', plays a set of gongs and gamelan-style instruments, creating swirling hammered tonal clusters that quiver beneath Henriksen's echoed-out, spirited improvisations. It's not always that corporeal, either; on 'A Remarkable Flow', he loops guitar phrases, creating gentle vibrations that rumble in the background while he mirrors Henriksen's pitchy zig-zags with high-pitched oscillator vamps.

Even on the peaceable 'Miraculous Lake', discreet kalimba loops set a celestial tempo that anchors the duo's gaseous soundscapes. And although they veer towards end-credits loveliness on the Göttsching-influenced 'Reunion Hymn', it’s balanced by the album's darker passages, like 'Rebirth' and 'Another Me'. On the latter, Henriksen's trumpet is transformed into a voice-like warble, while Jürjendal replies with glacial E-bowed drones that resonate creepily alongside his lysergic FM pads.
