Like I said a little over a year ago, Greta Van Fleet might just have to save Rock N Roll.

Well…looks like they are.

NEW YORK (AP) — When the members of the rock band Greta Van Fleet put their last touches on their first full-length album, they didn’t celebrate with a round of beers or a fancy dinner. They immediately started working on new songs.

“Once we finished ‘Anthem of the Peaceful Army’ — the very day that we’d OK’d all the mixing — we started writing the next album,” said Jake Kiszka, the band’s guitarist. “If we’re stagnant, it becomes boring.”

The young Michigan rockers whose sound and classic rock look is reminiscent of Led Zeppelin have done the opposite of stagnate in the last 18 months. It’s been more like an explosion, capped by four Grammy Award nominations, including best new artist and best rock album.

Since their April 2017 breakthrough with the song “Highway Tune,” they’ve put out two EPs and their “Anthem of the Peaceful Army” debuted at No. 1 on Billboard’s rock chart and No. 3 on the all-genre albums chart last year. It has also reached the Top 10 in Canada, Italy and Germany.

They’ve played “Saturday Night Live” and “The Tonight Show Starring Jimmy Fallon,” count Elton John as a fan and have been embraced as the four guys who can save rock ‘n’ roll, a tag they politely decline.

“It’s a silly thing to consider anyone a savior of rock ‘n’ roll. In our opinion, no one king can wear that crown,” said Jake Kiszka, 22. “There’s always someone who carries the torch and takes that into the future and interprets that through their influences.”

Jason Flom, who signed Greta Van Fleet to his Lava Records, said there’s nothing calculated about the band, saying they make music because it’s what they were born to do: “It’s almost like they were sent in a time capsule to save rock ‘n’ roll,” he said. “They wouldn’t say that, but I will.”
