Belgium-based composer Christina Vantzou's fourth full-length for Kranky ventures further into the uniquely elusive and evocative mode of ambient classical minimalism which has become her signature: a fragile synthesis of contemplative drift, heady silences, and muted dissonance. No. 4 took shape across roughly two years, incorporating a diverse array of musical and conceptual collaborators, including fellow Kranky artists Steve Hauschildt and John Also Bennett (of Forma) as well as Angel Deradoorian (ex-Dirty Projectors), Clarice Jensen, Beatrijs De Klerck, and members of Belgium's Echo Collective.
