He had recently asked for fans to send them their addresses, leaving no details or explanations for the slightly odd request. We pretty much trust him with our lives, so of course we just gave him all of our personal info without asking any questions.

One of the still missing pieces is the most important part: the date. Since the K. Flay assisted track is already out and Shinoda has noted wanting to create music videos for every Post Traumatic song, we’re assuming a video is what’s being teased.
