Alva Noto is the operating alias of Carsten Nicolai, and with Insen he continued the collaboration with Ryuichi Sakamoto that started with Vrioon. Nicolai's gossamer-like electronic processes combine with ethereal classic piano to create a tension filled conversation. At times barely there, in other places the minimal elements combine and lock in to each other in a powerful and moving way, like Reich at his best. Best listened to as the soundtrack to a contemplative journey, or a lost hour in an art gallery.
