Which two producers joined Taylor Swift for her Grammy performance of “august”?

Jack Antonoff and Aaron Dessner joined Taylor Swift for her Grammy performance of “august.” They accompanied her during the 63rd Annual Grammy Awards medley of “cardigan,” “august,” and “willow.”

Antonoff produced “august” with Swift and also contributed songwriting and instrumentation. Dessner was not a credited writer or producer of the studio track, but he was a central Folklore collaborator and produced many other songs on the album. His presence connected the performance to the wider sound and creative world of Folklore.

The three artists performed together for the first time at that ceremony. This detail can be confused with Joe Alwyn’s production credit: Alwyn helped produce “august” under the album’s personnel credits, but he did not join Swift onstage for the Grammy medley. The performance therefore featured Swift, Antonoff, and Dessner rather than all of Folklore’s credited producers.
