Going back and forth on Facebook posts with Mr. Active Child himself, it has come to light that there is indeed a split 7" single in the works with himself and tour mates School of Seven Bells.
(Side note: best tour pairing ever.)
It will feature each artist remixing a track from the other. SVIIB are tackling 'Curtis Lane' highlight "I'm In Your Church At Night" - for which there is a new video in the works, I imagine using the original EP version - while forthcoming single and 'Disconnect From Desire' highlight "Heart Is Strange" is getting an Active Child overhaul.
I cannot think of a way this could be any better.
