I was a little surprised that Jack White didn't end up here, given the late summer routing of his shows around the UK. Felt like an obvious slam-dunk of a pick.
Wolf Alice intrigue me. Headlining Tramlines, likely gearing up to make the push for R+L-type slots after selling out Finsbury Park... feels like it would have to be a proper coup-level shout.
This said, I am utterly stumped as to who it could be. Beartooth seem ripe for a high-end slot, but they've only got shows of their own this October - including Leeds.
