Greta Van Fleet sound like they did weed exactly once, called the cops, and tried to record a Led Zeppelin album before they arrested themselves. The poor kids from Frankenmuth, Michigan don’t even realize they’re more of an algorithmic fever dream than an actual rock band. While they’re selling out shows all over the world, somewhere in a boardroom, a half-dozen people are figuring out just how, exactly, Jimmy Page and Robert Plant are supposed to fit into the SUV with the rest of the Greta Van Fleet boys on “Carpool Karaoke.”

Just look at this photo: Brothers Jake and Sam Kiszka, on guitar and bass, are both wearing hippie costumes they 3D-printed off the internet. The singer, the wretched and caterwauling third brother, Josh, is in dangly feather earrings and vinyl pants, like he was dressed by a problematic Santa Fe palm-reader with a gift certificate to Chico’s. It’s a costume—Greta Van Fleet is all costume. And if things that look like another thing is your thing, get ready to throw your lighters up for a band whose guiding principle seems to be reading the worst Grand Funk Railroad songs as if they were a religious text.

Though their debut album, Anthem of the Peaceful Army, sounds like a bona fide classic rock record—with its fuzzy bass, electric sitar solos, and lyrics featuring the kind of self-actualized transcendence brought on by a few too many multivitamins—it is not actually classic rock. They are a new kind of vampiric band who’s there to catch the runoff of original classic rock using streaming services’ data-driven business model. Greta Van Fleet exist to be swallowed into the algorithm’s churn and rack up plays, of which they already have hundreds of millions. They make music that sounds exactly like Led Zeppelin and demand very little other than forgetting how good Led Zeppelin often were.

It’s possible to be an exceptional classic rock vampire act but it requires something more than the major label money and vaguely Native American accoutrements. It’s why Greta Van Fleet can’t compete with, say, the Darkness circa 2003’s “I Believe in a Thing Called Love.” The Darkness—who aped big rock warhorses like Queen and Aerosmith and Van Halen—were so outrageous that they had to be credulous. They had a song that went, “Get your hands off of my woman, mother fucker” and did a power metal cover of Radiohead’s “Street Spirit (Fade Out).” Who would do such garish things? They dared you, tongue in cheek, to take this impossibly foolish thing very seriously.

Greta Van Fleet do no such thing. They care so deeply and are so precious with their half-baked boomer fetishism, they mollycoddled every impulse of late-’60s rock‘n’roll into an interminable 49-minute drag. Each song here could be written or played by any of a thousand classic rock cover bands that have standing gigs at sports bars and biker joints across America (the same venues where Greta Van Fleet cut their teeth when they were kids). So why should Greta Van Fleet be the ones signed to Republic and William Morris, because they don’t have bald spots yet? Tons of people in those cover bands play their instruments better than Greta Van Fleet, who are, currently, proficient at best. No one in this band offers anything in the way of personality that doesn’t sound like your average YouTube tutorial for a Jimmy Page-type pentatonic solo or a John Bonham-type shuffle.

And at least Zeppelin knew to separate their sweet-lady-I’m-horny songs from their howling-about-literary-fantasy songs. Hilariously, Greta Van Fleet combine them into one on “The Cold Wind,” where the narrator (who is dying) begs his “sweet mama” to take the family ox (I guess) to town to sell it, when, mid-ox-transaction, this happens: “The Yankee peddler bargains with you on his way/Whoa sweet mama’s gotten herself a new dress.”

That’s funny, but it’s not supposed to be funny, because Greta Van Fleet do not possess self-awareness—at all. When asked about a characteristically ugh lyric (“All my brothers who stand up/For the peace of the land”), Jake responded, in part, “I guess it’s subject to interpretation. But I think the initial idea with that was that, as brothers, we stand for the peace of land. And that was for the good of the Earth, and for man.” Ignoring that this is basically a gag in Spinal Tap, a much better answer that would speak to the spirit of the music they are trying to capture would be: “I don’t know, who gives a shit.”

What they lack in self-awareness they more than make up for in rigid self-consciousness, failing to make any fun or campy choices to lift these songs out of a morass of the worst impulses of Rush and Cream. The back half of the album alternates between the ignorable and unforgivable, from what is (a somewhat fun stomper “Mountain of the Sun”) to what should never be: “The New Day” features Josh singing about watching a child grow in a garden, seeing her bloom so she can “be a woman soon.” None of this lysergic-sexual thinking is within the band’s grasp, they are just swatting at crusty platitudes and copy-pasting old mythos hoping no one notices that they are too small, too inept to even put forth one meaningful, specific, original idea.

But for as retro as Anthem of the Peaceful Army may seem, in actuality, it is the future. It’s proof of concept that in the streaming and algorithm economy, a band doesn’t need to really capture the past, it just needs to come close enough so that a computer can assign it to its definite article. The more unique it sounds, the less chance it has to be placed alongside what you already love. So when the Greta Van Fleet of your favorite artist finally lands on your morning playlist, spark up a bowl of nostalgia and enjoy the self-satisfied buzz of recognizing something you already know. It’s the cheapest high in music.
