The track follows lead single "3WW", which features vocals from Wolf Alice frontwoman Ellie Rowsell, in teasing upcoming album Relaxer.

"The brass was recorded at Abbey Road; the keyboards were done on a Casiotone that cost £1.05 on eBay; and no-one is quite sure where the key change came from," the band write on Facebook. "We hope you enjoy it."
