Which collaborator co-wrote Taylor Swift’s “august” with Swift?

Jack Antonoff co-wrote Taylor Swift’s “august” with Swift. Antonoff also co-produced the track, continuing a creative partnership that had already included Swift’s albums 1989, Reputation, and Lover.

For “august,” Antonoff created the instrumental first and sent it to Swift. Swift then wrote the lyrics quickly and intuitively, building a fictional late-summer romance around the music. Their collaboration helped produce the song’s hazy combination of guitars, keyboards, strings, and reverberated vocals.

Antonoff is sometimes confused with Aaron Dessner when people discuss Folklore, because Dessner was another major producer and collaborator on the album. Dessner worked on several Folklore songs, but Antonoff is the credited co-writer of “august” alongside Swift.
