Bloc Party's new album, Four (artwork above), is released on August 20 via Frenchkiss, but you can listen to it over at Bloc Party's website right now .

In keeping with the album's titular theme, the band are encouraging you to select four of your friends on Facebook to make up "your Four". Interpret that however you will, but get causing potential social havoc now.

The band's October UK tour is almost completely sold out - only their date at Glasgow's O2 Academy on October 14 still has tickets available - and they've just announced a show February 22 2013 at London's Earl's Court.
