Music inevitably lives with us as we experience our daily lives. Matthew Cooper makes music as Eluvium that seems to make the mundane more epic, the insufferable peaceful. His ambient washes of sound never feel smothering; rather, they are canvases of sound that open up new possibilities. The organ drones of “Don’t Get Any Closer” feel like a pan-religious ceremony. “Warm” lifts off from there and sends us through the clouds with angelic tones. “By the Rails” pulls us back in from drifting away with its heartbeat throb. Though Eluvium’s music favors drawn-out, slow-motion movements, there’s an emotional push-and-pull at its core that keeps it interesting as well as soothing, and Nightmare Ending is immaculately paced, such as the way the nearly nine-minute, more obscure “Unknown Variation” is followed by the short and straightforward piano piece “Caroling” — either piece might have fallen flat, if not for the other’s presence. Ira Kaplan of Yo La Tengo’s voice also makes a welcome appearance here on album closer “Happiness,” which will bring wide smiles to any fan of either (or both) acts. Why Cooper chose to title his latest album Nightmare Ending is anyone’s guess. It’s like a beautiful dream throughout.
