The maiden release on Bernhard Günter's Trente Oiseaux label, Warszawa Restaurant is one of Lopez' more subtle and quiet works. It consists of seven untitled tracks that hover at the limits of audibility and feature low-pitched drones with little internal variation other than volume. Hence, the release requires either a tolerance for external sound interruptions or a very quiet listening environment (preferably the latter). Lopez has compared his quiet pieces to blurred images in photography, which exist at the limits of visual perception as these sound works exist at the limits of audible perception. The relative formlessness of this work forces the willing listener to approach the piece from a different perspective than the entertainment standards imposed by most commercial music, and to pay closer attention to the stillness, to focus on the inner sound, and to confront issues relating to perception, time and space, details and broad strokes, and ultimately the listener's own awareness.
