Even though he namedrops himself in the title, Jay is nowhere to be seen in the clip. Instead, we get a sample of new instrumental music set against a video of a young man in a "Stay Black" t-shirt running away from some unseen doom. It's a compelling visual all on its own, and it indicates that whatever 4:44 is, it's got a lot of layers.
The music, which includes some creepy-sounding reversed bars, is promising too. Just a few dozen more hours and we get to see what all of this is about.
