Indie rock band Manchester Orchestra has the longevity and the success to be a staple of both the late-night talk show and festival circuits.

With their 2021 album, “The Million Masks of God,” the four-member, Atlanta-based outfit also shows its lyrical and thematic depth.

Touring behind “Masks,” Manchester Orchestra comes to the Roxian Theatre in McKees Rocks for a show at 7 p.m. March 18.

After having the opportunity to score a movie, the group’s lead songwriters, Andy Hull and Robert McDowell, felt pulled to create what they called “movie albums” — song compilations with a narrative thread, meant to be listened to in sequence.

The making of “Masks” was made more dense and challenging as it coincided with McDowell’s father battling cancer, a battle that ended with his death in 2019. The album loosely tells of a man encountering the angel of death and being shown snippets of scenes from his own life.

“It was a connection of life and art,” Hull said. “It was also a way to process through our grief for this tragic thing that happened in our families.”

As the band plays the album for live audiences, he said, “It’s been so cool seeing people connect with it, having gone through similar things. If we can put anything into the world that makes somebody feel heard or felt or connected, that’s a real positive thing to me.

“I think the thing I’m most proud of is that the album has a positive message at the end of it.”

For Hull, writing the songs also became an examination of his own faith, but not one that came with an epiphany.

“I’m probably more confused than I was when I started,” he said.

Audience members at the Roxian will hear most of the songs from the album.

“We’re playing a lot from it, but not the whole thing,” Hull said. “We have a pretty large discography, so we try to mix it in with other things we think people will want to hear.”

Hull, 35, founded Manchester Orchestra as a high-schooler living in the suburbs of Atlanta.

“The first time I wrote the name down and thought it could be the name of my band was in 2003,” he said.

The name was inspired by the city in England where the music scene fostered groups like The Smiths, The Buzzcocks, The Stone Roses, Joy Division, Oasis and New Order.

“We didn’t start touring until my last year of high school, when I home-schooled myself. We went on tour and have been active since the end of 2004, the beginning of 2005,” Hull said.

With six studio albums to its credit, the band has appeared on late-night television with David Letterman, Conan O’Brien, Jimmy Fallon, Jimmy Kimmel and Carson Daly. Their music has been used in television series including “Gossip Girl,” “One Tree Hill” and “The Vampire Diaries.”

The band has performed at major music festivals like Lollapalooza, Bonnaroo, Coachella, Reading and Leeds Festivals, Austin City Limits Music Festival and others. They also host The Stuffing, an annual Thanksgiving-time festival in Atlanta.

Hull and McDowell created the score for the quirky 2016 comedy, “Swiss Army Man,” starring Paul Dano and Daniel Radcliffe.

Going on the road at such a young age, Hull said he never had a day job, per se, “but it wasn’t like I didn’t work. It sure felt like a day job. I think it’s a young man’s or young woman’s game early on. There’s just an energy you have to have to go play 300 shows a year, but that’s all we learned to do.”

As they’ve gotten older and formed families of their own, band members have cut back on touring.

“Luckily, as we got larger as a band, we were able to do that and not have to be gone all the time in order to survive,” Hull said. “That’s been a really big blessing.”

More downtime hasn’t made Hull complacent, though.

“With something you love so much, it’s always a challenge,” he said. “The great thing is that art doesn’t have a ceiling; there’s always a place to push it more. I think I’ll stop if I get bored, but I have not been bored in the least yet.”

Along with singer/rhythm guitarist Hull and lead guitarist McDowell, the band includes Andy Prince on bass and Tim Very on drums.

Special guests on the “Masks” tour, Hull said, are “a great band from St. Louis called Foxing and a great band from Michigan called Michigander.”
