Jack White operates on his own timeline, so it’s not that big a shock that he just released a new song, apropos of nothing.

‘Battle Cry’ is a heavy-riffing instrumental, save from a few stadium-sized HEY! chants.

We have no idea whether it is part of a new album, the theme song for some dystopic battle-arena robots vs. humans style film, or something in-between. The riff also has that ‘Zero’ by Smashing Pumpkins vibe about it.

Give it a listen below, and star wildly speculating about a new album!
