To say Taylor Swift's Eras Tour is leaving everyone wonderstruck would be an understatement.

Distilling a 17-year discography as iconic as Swift's into one show sounds impossible, but the star has proven that no task is too daunting for her. And while she has conquered stadiums with ease before, The Eras Tour transcends her foregoing concerts with its all-encompassing three-hour setlist, high-level production and powerful pathos: its worldwide magnificence is pure magic.

Enchanting hundreds of thousands since March, Swift's latest tour is as delightful as it is influential, providing a perfectly satisfying mix of nostalgia and surprises in true Swift fashion. Even though the musician is technically in her Midnights era, the celebration of her remarkable career is undoubtedly historic — and she's determined to share the moment with other artists during her trek across the globe.

The Eras Tour has featured a cohort of rising and established stars, from 2000s rock staples Paramore to indie rockers like beabadoobee and Phoebe Bridgers. They all have that same sparkle of charm and creativity that made Swift a sensation, and they also share a passion for her beloved discography. To understand what it's like playing a part in such a historic tour, GRAMMY.com spoke with some of Swift's opening acts about performing for sold-out stadiums.

"I shed a tear because I knew that it meant Taylor really believed in me," OWENN, who was a backup dancer on Swift's 1989 Tour, said of his invitation to open for the tour.

From special epiphanies to hilarious backstage moments, OWENN and his fellow openers Gracie Abrams, beabadoobee, girl in red, and GAYLE take us along their Eras Tour journeys — all the way back to the very first night.

These interviews have been edited for length and clarity.

Tell us about the moment you were offered an opening slot for The Eras Tour. What did the invitation mean to you?

Gracie Abrams: Prior to ever dreaming about my own shows I dreamt about going on tour with Taylor… The invitation to join the Eras Tour felt like the biggest prank of all time. I was like, "this can't be right…"

It made my world stop and I just couldn't believe the scale of the honor. I still can't believe it, two months into playing the tour. It's the best for every reason and in every way.

OWENN: I was offered The Eras slot while I was on tour choreographing for Lil Nas X. It was definitely [a] moment that I will never forget… It meant that Taylor really believed in me and that my life was going to be forever changed.

beabadoobee: A serious pinch me moment! It was the end of last year, around the time I was doing "Jimmy Fallon" in December, and I was speaking with my manager about joining Taylor's tour as the main support. Funny because years ago I did an interview and mentioned how she would be my dream artist to go on tour with. I was thrilled to be a part of her Eras Tour.

girl in red: I was so stoked when I was offered to be opening act on the Eras Tour! I had never been to a stadium show, let alone play one, and the fact that my favorite artist invited me is just the coolest thing.

GAYLE: My manager and I — Kristina Russo, who has been my manager since I was 14 — were in my hotel room when she got a call and had a formal offer with all of the dates.  We cried, jumped around, and hugged.

My manager and I then surprised [my bandmates] by screaming "We're opening for Taylor Swift!" and they were shocked! We all hugged and cried, and I got two ice cream cakes from Uber Eats delivered to my hotel room, and we all ate them with plastic forks on the ground. It was truly one of the best days ever!

It was such an honor to be invited onto this tour. I know that's not a decision she takes lightly, so to be a part of that is the best thing ever.

Walk me through your first night on the tour. What was going through your mind? What was the energy like?

Abrams: The first day of tour I just remember walking into the stadium for soundcheck and crying laughing as soon as I heard my voice on the PA. It felt insane, to be honest, I felt crazy.

But then walking on stage, it was all of a sudden just about the community of people, the beyond dedicated die-hard fans who looked gorgeous and sparkly and committed to their outfits — it was about celebrating Taylor's legacy. It was like everyone in the room could feel the weight of it. I felt the most amount of gratitude, and I was also just internally bubbling with anticipation to watch her show on this tour for the first time.

OWENN: The first night on tour was insane! I rehearsed so much and trained really hard, but nothing could have prepared me for that level of energy and intensity ... from my vocals to me dancing in front of all of those people. It was definitely a surreal moment. Electrifying!

beabadoobee: Honestly every emotion. I would go through being extremely excited to terrified, to wanting to throw up all over myself and then back to being just so pumped to get out there.

The energy was incredible — the stadiums, the stage, the crew, and the fans were all so supportive too. I always caught some fans singing and dancing to my songs; that really surprised me!

girl in red: The first day we were playing I remember walking up on stage for soundcheck and getting really nervous about playing later cause it was so big. I was worried I'd mess up the words and make a fool out of myself, but luckily it went well!

GAYLE: Opening up for the first night on the Eras tour was such a high honor and I was so scared. I practiced a million times in my hotel room because I was so anxious that I was going to forget the setlist. I made my whole family and my best friend's family go to the first two shows in Arizona. I also randomly really, really, really wanted my brother to think I did a good job.

Everyone in the crowd was so excited to kick off the tour, and so many people hadn't seen Taylor live in so long! It was such a kind crowd, and there was so much excitement and energy. It will forever be a memory I keep very close to my heart.

How does this tour compare to other tours you've been part of? What makes it unique?

Abrams: Every single inch of this tour is unlike any other I've been a part of in the past. This is only my second year touring ever, and to have had the opportunity to see the inner workings of the biggest tour in the world so intimately is just the luckiest thing.

Everyone that I've gotten to know on the crew of the Eras Tour is an exceptional person. Everyone is so hard working and so passionate about their role in the tour, and that alone is inspiring, even more so to realize it is a direct result of Taylor's energy and attitude as a person and as a leader. I think everybody feels as proud and lucky as I do to be involved in any capacity.

OWENN: I feel like every tour is unique in its own way, but this one for sure is different for me because I'm singing instead of dancing in the background. A completely different experience!

beabadoobee: The sheer size of everything, how professional Taylor is, and of course how it felt like we entered her world. She played for three plus hours and she looked like she didn't break a sweat. She's a superstar through and through and one of the nicest people on top. Really inspiring to see her perform to like 100,000 people yet still make you feel like she's playing and singing to just you.

girl in red: I think the biggest difference is the scale of the venue and that people might not know who you are. People are there to see Taylor, so the crowd chemistry is a little different and you have to adapt to that! 

GAYLE: Well, Taylor was my first stadium tour ever — which is the craziest thing to say ever. With other tours I've been on, I can distantly remember at what age I heard their songs and fell in love with their music. I fell in love with AJR when I was 12. I fell in love with P!nk when I was 10, thanks to my mother. I got obsessed with My Chemical Romance when I was 14, and I heard Tate McRae when I was about 15 and I loved her music. I've heard of Taylor Swift my whole entire life and there was never a point in my life where I didn't know and love her.

Share a special backstage moment — anything fun, silly, memorable that happened.

Abrams: I honestly just feel so lucky to be going through this tour with my crew and band, every one of whom are my second family now, the people I love more than anything and trust so deeply and laugh so hard with. I think for all of us having the opportunity to lean on each other as we've gone through these milestone firsts has been really formative.

OWENN: A very special backstage moment for me is when myself, my band and team all join hands in a circle and say a prayer. It's a beautiful moment for me as we're all connected and about to go on stage.

beabadoobee: We got to hang out backstage and just have fun, have a laugh and speak about our cats and whatever was on our minds. She's the loveliest person and even that she made the time meant a lot.

girl in red: I think the most memorable part of the tour, aside from playing my show, is getting to see Taylor play her show. After my show, I get ready to see her put on the performance of a lifetime and it feels like I'm in a very special time in my life. Very happy to be here.

GAYLE: I get very nauseous before and after I'm on stage and once, I walked off stage and started vomiting everywhere. The trash can was unfortunately right where Phoebe Bridgers was walking on stage, so I wished her and her band good luck as I was vomiting.

What have you learned from watching Taylor's show? What's been your favorite song to hear live or a memorable onstage moment?

Abrams: Watching Taylor's show is like watching an Olympian. Watching Taylor's show is also like sitting in a tiny room and sharing secrets with your best friend. There's a strength and a sensitivity to her show that is unlike anything I have ever seen or heard of in my entire life, with the exception of knowing her as a friend.

She is as rare a person as she is an artist and performer. I think the most popular opinion in the world right now is that Taylor's show is the best in the history of time. To watch and study the ways in which she's able to hold herself fully, while also carrying these stadiums of so many tens of thousands as they sob and dance and laugh and scream, is just unimaginable until you're lucky enough to see it for yourself.

OWENN: I actually have a couple of favorite things. When Taylor goes through the 1989 and reputation eras, I have flashbacks of those tours from the memories with her and the dancers to the actual choreography, it's so nostalgic!

And the opening of The Eras Tour! "Miss Americana & the Heartbreak Prince" is actually one of my favorite songs from Taylor so that's always a treat.

beabadoobee: I think the biggest take away is hearing her amazing songwriting. She really has a knack for making incredible songs and storytelling, being so direct with her words and lyric choices, I personally love that!

It was mind-blowing watching her go through each era and nail everything — all the costume changes, the acting theatrical elements to the show, and of course her insane stamina to go for more than three hours every night. I've never seen anything like that.

My favorite moment has to be when she dedicated "Our Song" to me and then played it on the first night. That song means so much to me and I mentioned in an interview a while back how it was my ringtone when I was younger and shaped my childhood. It was awesome!

girl in red: I've learned so much from seeing her performance, but I think what sticks out the most to me is how perfected the show is and how that truly just reflects Taylor as an artist. She has created all this beautiful and fantastic music and now she's made the most entertaining show. I'm so inspired by her work ethic and she really puts the work in – and that's why she is the best.

GAYLE: "Cruel Summer" is a hit and the best thing ever! Also "my tears ricochet" kills me, but also "champagne problems, " but also "Bejeweled." Also, watching Ice Spice and Taylor play "Karma" together was iconic!

I've learned that Taylor Swift is a beast and can do the impossible — sing for three and a half hours for three days straight, and for multiple weekends in a row. She paces herself beautifully and the way she paces her setlist is amazing. [She] is captivating from beginning to end.
