Joe Alwyn shared production credit with Taylor Swift and Jack Antonoff on “august.”
The song’s credited producers are Swift, Antonoff, and Alwyn. Antonoff supplied the initial instrumental, while Swift wrote the lyrics and contributed to the song’s finished production. Alwyn’s production credit is part of the Folklore-era collaboration that was initially presented under the pseudonym William Bowery on some album credits.
This question concerns the original production credit for “august,” not the later Grammy-credit correction associated with another Folklore track. That distinction is important because Alwyn’s name appears in several discussions of the album’s production and songwriting.
Aaron Dessner was Folklore’s other principal producer and produced many of the album’s songs, but he is not listed as a producer on “august.” Jonathan Low worked as an engineer and mixer, not as one of the song’s three credited producers.
