Lil Wayne and Rick Ross, supported by a shadow-stalking, platinum-toothed Birdman, put on a big bass, future-animated-GIF clinic here, taking over what looks like the set of Kanye’s scrapped “Monster” video. “John” is the opposite of a backyard Pontiac showcase: nothing is pretty but every shot deserves a screen grab. Lil Wayne is apparently insanely jacked now, setting up a stark contrast with Rick Ross in a wheelchair, which is the greatest rap pose. Speaking of the near future, the alleged cover for Tha Carter IV has been floating around. We’re taking this with a grain of salt, but we couldn’t really believe the Carter III baby until we held him in the checkout line.
