They were hard-pressed to top last year’s Potato Wars showdown, but on this season of every Britpop enthusiast’s favorite reality show, The Gallaghers, we’ve been treated to the most dramatic story arc yet. For the first time in their post-Oasis careers, Liam and Noel have each released albums within weeks of each other, setting up the proverbial WrestleMania of rock’s greatest sibling rivalry. Alas, it remains to be seen whether Noel’s latest record with current backing band the High Flying Birds, Who Built the Moon?, will match the chart performance of Liam’s recent solo effort, As You Were, which debuted at No. 1 in the UK. But in the real arena where winners are made and losers are shamed in 2017—i.e., Twitter—Liam has been putting on a clinic, delivering some his best material ever in the wake of what will go down in Gallaghers lore as Scissorsgate.

For his part, Noel seems to be heeding the lesson learned from Oasis’ rivalry with Blur throughout the ’90s. Only, in this case, he’s decided it’s better to be Blur—to brush off the nasty insults, disengage from the war of words, and just focus on making far more interesting records. Where Liam’s As You Were is essentially the perfunctory Fauxasis album that his old band would’ve churned out this year had they slogged it out this far, Who Built the Moon? feels like an attempt to rewrite their post-Morning Glory history.

The album imagines an alternate late-’90s where, instead of trying to make a cocaine-clouded update of Magical Mystery Tour, Noel deeply internalized the adventurous music being made by his peers in Primal Scream, Spiritualized, Death in Vegas, the Beta Band, and David Holmes (whom he wisely taps to be his producer this time out). The new album’s opening track, “Fort Knox” presents an immediate study in contrasts. Like the kick-off to 2000’s Standing on the Shoulder of Giants, it’s more of a crowd-rousing entrance theme than a proper song—but instead of bluesy guitar riffage, we hear screeching cello drones, clanging percussion, gospel chants, a hip-hop-scuffed backbeat, the relentless drill of a jackhammer, and a female backing singer’s ecstatic wordless wails. Call it “Kama Sutra in the Bushes.”

Sure, there are few prizes for being on the cutting edge of circa-1997 British rock in 2017, but Who Built the Moon? abounds with urgency and absurdity—qualities that were sorely lacking on the Birds’ previous albums. For the first time in a long while, Noel sounds like he’s genuinely having a blast, adopting a motor-mouthed monotone on the glam-slammed rumble “Holy Mountain” as if he were Plastic Bertrand doing “Diamond Dogs,” and blissfully skating atop the glacial motorik surface of “She Taught Me How to Fly.” And just as the skittering psych-pop of “It’s a Beautiful World” seems like it’s about to dissolve into the ether, he summons guest vocalist Charlotte Marionneau of indie-pop enigmas Le Volume Courbe to deliver a surprise megaphoned address that revives the song as a Francophone answer to “6 A.M. Jullandar Shere” by former Oasis tourmates Cornershop.

Who Built the Moon? feels like the sort of album where Noel spent way more time mapping out the sounds than writing the lyrics. But “Keep on Reaching” whips up enough manic, soul-stomping gusto to forgive its obvious Stevie Wonder swipes (”Keep on reaching out for that higher ground”), while “Be Careful What You Wish For” oozes enough creeping menace to elevate its title from clichéd phrase to prophetic threat. Alas, in the album’s closing stretch, Noel attempts to inject the proceedings with some conceptual gravitas, deploying a pair of moody instrumentals (dubbed “Interlude” and “End Credits”) to bookend the winsome, swashbuckling pop of “If Love Is the Law” and the climactic foreboding ballad “The Man Who Built the Moon.” With no discernible logic holding it all together, the result is a more of an awkwardly fitting framework than a proper song suite, though at the very least, the latter track’s ominous, In the Court of the Crimson King-style grandeur does raise the not-unwelcome notion of Noel going full prog.

But more than any particular musical experiment, the best gauge of Gallagher’s growth on Who Built the Moon? is the song that didn’t make the cut. Included as a bonus track, “Dead in the Water” is a quintessential Noel solo strummer, an unplugged transmission from the same dark night of the soul that yielded acoustic Oasis outliers like “Talk Tonight.” It’s a great song, right up there with Oasis’ best B-sides. But it’s one whose raw emotion and bare-bones simplicity represent low hanging fruit on the High Flying Birds’ current skyward path.
