Bloc Party have given us a taste of what their upcoming LP Four, their first since 2008's Intimacy, sounds like, debuting 'Day Four' from the album on the Australian radio station triple j - have a listen below.

It's not the first we've heard from the new album: they've already released new single 'Octopus' digitally, and it gets a physical 7" release on August 13.

'Day Four's wash of arpeggiating guitars suggests a move back to the sound of their early EPs and debut album, 2005's Silent Alarm; we'll know for sure when the album is released on August 20, via Frenchkiss.

In the meantime, have a read of our live report from their gig at KOKO in June and watch the video for 'Octopus' below:
