Deafheaven have released a surprise new single in the form of a b-side from their latest album Ordinary Corrupt Human Love. Called 'Black Brick', it's a seething seven minutes of straight black metal madness, devoid of any post-rock or ambient inflluences often found in any other material from the band. In fact, we'd go as far as saying it might be one of their heaviest songs to date.

Check it out:

 Deafheaven are currently on tour throughout Australia and have already begun performing this track at their live shows. They will play their final show of the tour at Sydney's Manning Bar tonight.
