‘Alluvium’ is the fourth album from C Duncan, Glasgow’s classically trained multi-instrumentalist and singer-songwriter, released through Bella Union. After the haunting raptures of Architect (2015), the Twilight Zone-inspired reveries of The Midnight Sun (2016) and the richly melodic Health (2019), Alluvium is a sublime palate-refresher for Duncan (C for Christopher), brimming with revitalised fluency: a warming dispatch from the daylight zone, if you like.
