A Los Angeles-based band thanked their fans for their patience after the venue they were playing in was evacuated.

Indie rock band, Mt. Joy, was due to perform at the Ascend Amphitheater in Nashville, Tennessee on Tuesday but fans were asked to leave the open-air venue due to lightning in the area.

The amphitheater kept fans updated via its official X, formerly Twitter, account over the course of a few hours.

“Due to severe weather and lightning in the area, we are currently delaying doors for tonight’s show. We are actively monitoring the incoming weather and will provide prompt updates when we are able to safely begin entry to Ascend Amphitheater,” it first wrote at 6:30 p.m. local time on Tuesday.

The doors eventually did open but then venue management decided to get everyone out for their own safety.

“8:15PM UPDATE 🚨 Due to lightning in the area, we are evacuating the venue at this time. Please calmly proceed to the nearest exit and seek shelter,” read the venue’s X account.

It continued to update the music fans saying it was monitoring the weather situation and then almost an hour later declared, “we’re putting the joy back in Mt. Joy. We’re opening doors soon.”

The doors to the amphitheater reopened at 9:15 p.m. and the concert went ahead as planned.

Mt. Joy took to its Instagram stories after the concert to thank fans for their patience.

“Nashville, thanks for sticking it out with us,” it captioned a photo of the band posing on stage in front of the crowd.

Newsweek contacted Mt. Joy’s management by email for comment.

Mt. Joy is best known for its 2015 song, “Astrovan” and is made up of, Matt Quinn (vocals, guitar), Sam Cooper (guitar), Jackie Miclau (keyboards), Sotiris Eliopoulos (drums) and Michael Byrnes (bass).

The band is named after a mountain in the Valley Forge National Park in Pennsylvania where Cooper and Quinn hail from.

Earlier this month, the band returned to Cooper and Quinn’s home state to play at The Mann Center where it teamed up with a local food bank to help fight food insecurity in Philadelphia. Fans who donated food went in a draw to win the chance to watch the concert from the side of the stage.

“For us to be able to play that stage, it is literally like a sixth, seventh grade dream come true,” Cooper told PBS’ Whyy ahead of the concert.

Quinn also told the news outlet: “We have a lot of people that are now coming to these shows.

“Let’s just make our shows as fun as possible, and make sure these people are seeing one of the best bands out. [We want] to make sure they’re leaving and feeling like that was one of the best shows they saw all year.”

Evacuating open-air venues in the event of a storm is not uncommon, as Taylor Swift fans learned in Australia earlier this year.

Swift’s first show of her Eras tour at the Accor Stadium in Sydney was partially evacuated due to lightning strikes near the stadium.

Fans were eventually let back in and Swift’s sold-out show started at a delayed time, going ahead without a glitch.
