Write this down, plug it in your Google Calendar, do whatever people do to keep track of their dates: The xx will be on Conan next Tuesday, promoting their new album Coexist (out September 11). It's a good music week for Conan O'Brien — Tennis will be playing on Wednesday. Will The xx play first single "Angels," or bust out some new material? Looks like you'll have to hit tune in to TBS and find out. Whether you fill the interim watching The Big Bang Theory reruns is entirely up to you. Listen to "Angels" below.
