This music, jointly composed by ethereally beguiling Norwegian trumpeter Arve Henriksen with his celebrated compatriots Eivind Aarset (effects guitar) and Punkt Festival founder Jan Bang (samples) wasn't conceived for a performance or recording. Commissioned by the city of Hull in 2017 when it became a UK City of Culture, the work was intended as headphone accompaniment to a public ‘sound walk’ through Hull and across its Humber Bridge – but the sell-out popularity of that event, extended from one month to three, spurred a permanent document. Henriksen's eerie, diaphanous trumpet sound is naturally the centrepiece, while his instrumental partners and Opera North's chorus and orchestra weave tapestries of distant chants, rich harmony, electronic textures, and field recordings of industrial and windy-landscape sounds. Apart from the leader's spinetingling early-Miles tone at times, explicit jazz associations are few – but though a sight of Hull's cityscape and a sense of its seafaring traditions do feel like missing elements in this cinematic work, the music does establish a powerful sense of place.

Henriksen's low horn murmurings over rising and fading strings and unearthly sighing electronic tones on ‘Reefs And Roots’, his countertenor vocal against woodwinds turning to wilder surges of sound on ‘Is There A Limit For The Internal’, and the slow-weaving cimbalom-like groove emerging from an oblique trumpet melody on ‘Waders’, are highlights of this venture's quietly compelling authority – and its rightful place in its primary creator's diverse discography.
