Vesper Sparrow continues Ellis's ongoing study of the intersections between music and sound, stuttering, and Blackness, through the lens of time. Rooted in Ellis's connection to Black religious tradition and inheritance, the album weaves granular synthesis, pop production, spoken word, and Caribbean and Black American musical lineages into atmospheric soundscapes shaped by saxophone, organ, hammered dulcimer, electronics, and their voice. Ellis chipped away at large slabs of recordings to reveal the album like a marble sculptor.
