Previously known for his balance of guitar-washed drone and ambient noise, Matthew Cooper's Eluvium project shows maturation through controlled simplicity on Copia. Without guitars, the record lends a sense of timelessness to Eluvium's pastoral pieces. At times, as on "Prelude for Time Feelers," his work surpasses his peers', achieving a level of sincerity on par with composers like Arvo Pärt. Even less structured tracks, like "Seeing You Off the Edges," are clear and intentional. By subtracting layers and letting his compositions stand on their own, Matthew Cooper has created a profound and lasting record.
