Nice little Monday surprise: The National and Bon Iver have just released a new song together.

Today, The Natioal shared their new single "Weird Goodbyes," a collaboration featuring Bon Iver's Justin Vernon. It's out now via 4AD.

“It’s about letting go of the past and moving on, then later being overwhelmed by second thoughts,” says The National frontman Matt Berninger of the track, which also features strings by the London Contemporary Orchestra orchestrated by bandmate Bryce Dessner.

Brother and bandmate Aaron Dessner says: “‘Weird Goodbyes’ was one of the first new songs we made. I was misusing drum machines, as usual, and stumbled onto this beat that got stuck in my head—it felt like something only Bryan [Devendorf] could naturally play. We built the song around the beat. Matt's melody and words felt so elegant and moving from the beginning—mourning a loss of innocence and motivation, holding onto memories and feelings that inevitably slip away and the grief we all suffer in weird goodbyes.”
