DIIV's dream-sequence soundtrack "How Long Have You Known" has been out for a while, but hadn't received a formal music video until now. The visuals feature the group's bleach-blonde moptop lead singer Zachary Cole Smith concocting a really crazy milkshake, with dangerous ingredients like a plasma globe, the guts of a lava lamp, and a cut out part of an American flag (which I'm pretty sure is illegal). There's a Party City in Brooklyn that did some good business that day. AND THEN HE EATS IT. Oops, spoilers. Check out the video below.
