A four-piece working-class band out of the Circuit's Duwamish Ward, Corridor Psalms built their reputation playing shift-change crowds at fabrication hall loading docks and union halls with busted PA systems. Their sound draws on West African kora patterns filtered through Appalachian drone, layered with the quarter-tone vocal traditions of the old Levantine diaspora — a music that feels simultaneously ancient and distinctly of the megacity. Lead vocalist Amara Solís-Okafor has a voice described by the Circuit press as 'a bruise that sings,' and the band's rhythm section — drummer Jakub Nweze and percussionist Celestine Huang-Ferreira — creates polyrhythmic patterns that somehow feel like a work shift: relentless, purposeful, almost meditative in their grind.

Their 2219 album 'The Seam Holds' became an unofficial anthem for the Municipal Services strike of that year, with the track 'Weight and Wages' played over pirate broadcasts on every striking shift. Vantablack Media's Circuit-facing subsidiary Ironclad Sound offered them a contract twice; they declined both times, citing creative control clauses that would have barred them from performing at Tier 1 venues. They remain self-released on physical chip media, sold at shows and through Circuit mesh networks.
