Joe Alwyn is the credited co-producer of Taylor Swift’s “august” associated with the pseudonym William Bowery.
The song’s main production credits are Taylor Swift, Jack Antonoff, and Joe Alwyn. Swift and Antonoff are the songwriters, while Alwyn received production recognition after Folklore won Album of the Year at the 63rd Annual Grammy Awards. He was credited under the name William Bowery, a pseudonym also used for his work on other Folklore songs.
This credit is often confused with the songwriting credit. “August” was written by Swift and Antonoff, and Antonoff developed the instrumental before Swift wrote the lyrics. Alwyn’s recognized contribution concerns production rather than the publicly listed songwriting partnership.
Alwyn’s involvement became more widely discussed because Folklore deliberately blurred autobiography and fiction while revealing several collaborators only through credits and pseudonyms. The Recording Academy later recognized his work in connection with the album’s Grammy win. That makes him a particularly notable behind-the-scenes name in the history of “august.”
