There’s something scary about children. No wonder many horror movies feature kids as the main source of horror. Bloc Party’s new music video, Kettling, starts with children playing British Bouldog, a game that slowly turns into a bloody violence as the video progresses.

Here’s what band’s frontman Kele Okereke said about Kettling’s music video: “There was so much going on in the world in 2011. You couldn’t turn on the television without seeing pictures of people protesting or rioting or mass disarray. Of course those are quite frightening images. But there’s also something quite poetic about people standing up and saying they’ve had enough of something; that no, they will not take this any more. That’s what the song was really about.”

The word “kettling” is a definition of police tactic used for taking the crowd under control during mass protests and demonstrations.

The song is featured on Bloc Party’s new album, Four, released this summer. Ignoring the latest tendencies, the album consists of guitar-driven songs instead of recently popular dubstep music and alike.
