LAS VEGAS (KTNV) — Just when you thought they couldn’t fit any more emo and punk music into Las Vegas, they cook up a second day of the When We Were Young festival.

And despite earlier doubts from social media, it seems it’s as legit as they come.

Bands, organizers: It's happening

The sold-out festival will now take place on Oct. 23 as well as its original date of Oct. 22 at the Las Vegas Festival Grounds. Both days will have the same lineup.

The second date was added due to high demand, organizers say.

“You’re like, ‘Alright, that lineup is so stacked. It’s got to be fake.’ But it wasn’t,” said Matt Jozwiak, a ticketholder from Chicago, Illinois. “And I have no doubt in my mind that it’s going to plan out pretty well.”

The show's legitimacy has been called into question by some on social media. Rumors that some of the bands did not know that they were booked until it was announced are untrue, organizers tell 13 Action News.

It's possible the rumors started as a misunderstanding from a tweet.

The All-American Rejects shared a picture on Twitter of the event's flyer, which showcases the 65 bands set to perform, saying"Apparently we’re playing with ALL the bands…"

Since its initial announcement earlier in the week, more and more of the headliners have confirmed: yes, this is really happening. Headliners Paramore and My Chemical Romance were quick to share out information about the event on Twitter.

The lineup is packed with artists popular in the 2000s. Bands like AFI, The Used, Taking Back Sunday, Dashboard Confessional, Alkaline Trio just to name a few.

The nostalgic lineup has led a ton of buzz online.

"It just hits me right in the heart,” said Jozwiak.

Addressing safety concerns

One thing that's also being talked about online is the fact that the festival is put together by Live Nation, the same group that organized Astroworld in Houston last year.

Live Nation is the largest live event promoter in the world and operates T-Mobile Arena.

Entertainment experts say deadly events like Astroworld are rare, and however tragic, it pushes companies to adjust to keep people safe.

“Live Nation has been set up in the industry for a long time,” said Jasmin, a ticketholder from San Diego, California. “Although there was the recent incident that happened—that, more than anything, is just a sign that they’re going to take even more precautions.”

When We Were Young put out a statement saying:

Hope is high, but there are some cracks in the foundation.

“You take a look at the general admission, it doesn’t specify what day we’re going,” said Rory Frazee, a ticketholder from Indianapolis, Indiana. “It just says either of those.”

With 65 artists across three stages that doesn’t leave too much time, though Live Nation said to expect the headliners to play for as long as an hour apiece.

“It’s going to suck that you’re going to miss someone that you like, but in the meantime, while you’re missing someone you like, you’re also enjoying someone that you like even more,” said Jozwiak.

“This being one of the biggest sellouts in a really long time, there’s going to be no worry to it and they’re going to be prepared,” said Jasmin.

Tickets start at $224.99 for general admission. More information can be found on the festival's website whenwewereyoungfestival.com.
