Joe Alwyn co-produced Taylor Swift’s “august” alongside Swift and Jack Antonoff.
The song’s production credits list Swift, Antonoff, and Alwyn. Antonoff created the instrumental first, while Swift wrote the lyrics after receiving it. Alwyn was credited as a producer under the pseudonym William Bowery on some Folklore and Evermore material, though the “august” article lists Joe Alwyn directly in its credits.
This detail is easy to miss because Alwyn is more widely known as an actor and as Swift’s former partner than as a studio collaborator. His production work formed part of the close, home-recorded creative process behind the pandemic-era albums.
Aaron Dessner is another important Folklore producer and songwriter, but he is not the answer for this track. The distinction matters because several collaborators worked across the album, while individual songs have different writing and production credits.
