Jay Z & Justin Timberlake "Holy Grail" (Anthony Mandler, dir.)
There's a last days of Xanadu vibe here, with Jay Z and Justin Timberlake all alone at the top of the world, surrounded by the baubles that come with great wealth and success — an effect that's further emphasized by the periodically slurred-down audio.
Also of note is that this is the first Facebook exclusive premiere, with the video available exclusively via Facebook and giving Jay Z and Justin Timberlake unfettered reach to their combined 42 million followers (which if you know anything about how Facebook posts are limited unless boosted, you know the value of that promo is huge).
And it could be a good case study into whether people care about where or how they watch videos, so long as all the sharing/embedding features they expect are supported.
