Now available as a double vinyl version, 2007's Walls is the fifth full-length album from Berlin-based musician Apparat. Despite its title, Walls isn't about dividing lines. Instead, it describes a circle that pulls many elements together into a protected, enclosed space where they jostle and roam free: strings and mallet instruments; rock guitar and gravelly sawtooth synths; stuttering digital percussion and muscular studio drumming. Important guests and collaborators on this record include Telefon Tel Aviv's Josh Eustis, who did the album's final mixdown in Chicago, as well as the talented Raz Ohara, who contributes his smokey vocals. Apparat has melded his genius as a sound designer with his growing songwriting talents to craft songs brimming with ideas, energy, texture, light, color. They are hummable, embraceable, swimmable, possibly edible.
