There is no slowing down for Taylor Swift. Fresh off debuting her song “I Knew You Were Trouble” at the American Music Awards earlier this month, Taylor decided on a stripped-down version while performing the song in Australia.

Seated side by side with her two guitarists, Taylor joins her band on acoustic guitar where she shows off her vocals. Alternating between whispered singing with a slight echo it’s easy to hear the heart and passion of the song within Taylor’s approach.

It’s a very different version of the song than the one appearing on Red–which she’d previously called one of her favorites on the album.

Are you curious who the song might be about? Keep on guessing, because Taylor has already said she will never tell.
