WATCH: New Bloc Party vid

Bloc Party have unveiled the video for 'Octopus'. The track is taken from forthcoming album Four, due out on August 17.

There were rumours that the Londoners were to replace frontman Kele Okerake for the project, but speaking to Zane Lowe on BBC Radio 1 earlier this year, Okereke confirmed that the band had been working in New York on Four.

Okereake released two solo albums, The Boxer in 2010, and The Hunter in 2011, since Bloc Party's last release - 2008's Intimacy.
