Which two producers co-produced every track on Taylor Swift’s The Life of a Showgirl with her?

Max Martin and Shellback co-produced every track on Taylor Swift’s The Life of a Showgirl with her.

The album’s principal production team is Taylor Swift, Max Martin, and Shellback. Their collaboration gives the record a consistent pop-focused sound while incorporating soft rock, new wave, disco, strings, horns, piano, guitars, synthesizers, and keyboards.

Martin and Shellback had previously worked with Swift on Red, 1989, and Reputation. Their reunion for The Life of a Showgirl marked a return to collaborators associated with some of Swift’s most polished pop recordings. Unlike several earlier Swift albums, the project does not list Jack Antonoff as a producer.

The wording “every track” refers to the standard album’s production credits, not every musician or engineer involved. Many additional artists contributed instruments, recording, editing, mixing, mastering, photography, and packaging.
