Bloc Party will release their first album in four years, which just so happens to be named Four, on Aug. 21. And we're getting a strong sampling of the record here in lead single "Octopus," which just received some flashy, stylish visuals. They center on stuttering shots of the band, footage of dancers with ribbons and hula hoops, and plenty of effects. You can watch the colorful, sorta-wild video above and you can pre-order the album on Amazon.
