German DJ and producer DJ Koze (aka Stefan Kozalla) is back with Knock Knock, his first studio album in five years. For it he's lined up an impressive set of guests, including Bon Iver, Róisín Murphy, Kurt Wagner of Lambchock, Speech from Arrested Development, Jose González, and Sophia Kennedy. You can check out the gorgeous, lightly house-y "Seeing Aliens," and its equally inticing B-side, "Nein König Nein," below.
