Meghan Trainor, Adam Lambert and Fifth Harmony Remember Their First Concert Ever

You never forget your first concert. For me it was KIIS FM's Wango Tango. The year? 2003. The artists? Christina Aguilera when she went by "Xtina," Nelly when he was rocking that band-aid on his face and 'N Sync's J.C. Chasez when he went solo for a second, among others.

It was memorable to say the least. So imagine my excitement when I covered this year's Wango Tango festival on Saturday, which included headlining performances from Kanye West,Justin Bieber and Calvin Harris.

Turns out I'm not the only one who is nostalgic about their first concert. Here’s what some of the stars had to say about their first live music experience.

Adam Lambert: "My first show? I think I saw Paula Abdul as a kid."

Jason Derulo: "A Michael Bolton concert. My mom was obsessed with Michael Bolton so that was actually my first concert."

Fifth Harmony
Normani: "My first was Alicia Keys."
Camila: "My first was Justin Bieber."
Ally: "Mine’s funny-- the Trans-Siberian Orchestra."

Ne-Yo: "My first concert was New Edition. And it was New Edition when they were all together: Ronny, Bobby, Nicky, Mike, Johnny Gill, like all of them. And they had these red suits with embroidered tiger over the front with these red embroidered caps and I was like this is what I want to do with my life."

David Guetta: "It was Earth, Wind and Fire (laughs hysterically). That bad?"

Ryan Seacrest: "Richard Marx. Richard Marx the 'Right Here Waiting' Tour he came out of the floor with a piano at the Fox Theater in Atlanta and then my second was Bon Jovi."

Meghan Trainor: "'N Sync. It changed my life. Made me realize I love boys."

R5: "Backstreet Boys. 'Larger Than Life' Tour."

Jake Miller: "'N Sync. I was still being bathed by my parents in the bathtub when they surprised me with the tickets."
