At which event did Taylor Swift first perform “august” live in 2021?

Taylor Swift first performed “august” live in 2021 at the 63rd Annual Grammy Awards.

The performance took place on March 14, 2021, as part of a medley with “cardigan” and “willow.” Swift began with “cardigan,” performed “august” inside a cottage while playing guitar, and concluded with “willow.”

Jack Antonoff and Aaron Dessner accompanied her, making it the first time the three Folklore producers performed together. The staging used a woodland cottage and matched the album's atmospheric, cottagecore presentation.

The Grammy appearance came before Swift later included “august” in the Folklore section of the Eras Tour. This makes the awards-show performance an important early live milestone for a song that was initially released as an album track.
