A.M. Architect is a Boston-based beat duo whose third record, Pattern Language, saw release via Toronto's Urbnet back in February. Album highlight "Window" has just been offered up as a free download—along with a stuttering edit of the track, which can be nabbed here. The tune is notable for its microscopic attention to detail, with its lush piano lines and evocative vocal sample layered over broken, distorted beats. A.M. Architect also shared along with its tune a new mini-documentary from Studio Feed, which details the origins of the pair's project, after the jump.
