Taylor Swift‘s much-buzzed-about The Eras Tour is set to begin on Friday (March 17) with back-to-back shows in Glendale, Ariz., and the superstar gave fans a little peek into her rehearsals.

The “Anti-Hero” singer took to social media to share a series of photos of herself rehearsing her set onstage, dressed in olive-colored cargos, a black crop top and, of course, a red lip. “In my Eras era,” she captioned the post, which also included a photo of her multi-colored nails, which seems like each fingernail represents one of her 10 studio albums.

Swift also shared a sweet picture to her Instagram Stories of a hand-made “All Access” credential she made for her father. “D.O.H. Pass (Dad of Headliner),” the pass reads, as Swift jokingly wrote underneath, “We are a small family business.”

Her dad, wearing his new pass, then teamed up with Swift’s mom to put crystals on their famous daughter’s Fearless-inspired guitar “with super glue and a free afternoon.” Check out the multi-Grammy winner’s recap of her last rehearsal day on her Instagram Stories before they disappear here.

Earlier in the day, the “Blank Space” superstar surprised Swifties by announcing that she would be dropping four new songs ahead of her tour kickoff. “In celebration of The Eras Tour I’m releasing 4 previously unreleased songs tonight at midnight,” she revealed on her Instagram Stories. The four tracks include re-recordings of Swift’s dual contributions to the 2012 soundtrack to The Hunger Games — “Eyes Open” and “Safe & Sound” featuring Joy Williams and John Paul White — as well as “If This Was a Movie (Taylor’s Version)” and never-before-heard song “All of the Girls You Loved Before.”
