It was a hot and sleepy Tuesday evening in Allentown, a Pennsylvania Rust Belt city known for its colonial-era rebelliousness. Two blocks up the street from a grand steepled church that once hid the Liberty Bell from British forces occupying Philadelphia in 1777, is the shiny marquee of Archer Music Hall, the Lehigh Valley’s newest concert venue. Hidden away inside and vaulting artfully over angular rhythms and riffs were White Denim, the band of road warriors who’ve been searing the edges of the indie rock world—in one formation or another—for the better part of two decades.

In quintet form, the band took the stage 20 minutes early, riding the high from a day spent strumming historic guitars at a shop in nearby Bethlehem—a “top tenner” among his touring days, proclaimed frontman James Petralli later in the set. And so it began with “Pretty Green,” the driving thumper off of 2013’s Corsicana Lemonade which built to a dueling guitar southern rock crescendo.

“Light On,” the opening track on the latest White Denim offering 12, followed in swinging pleasantries, before a quick throttling via “Sky Beaming.”

Any lingering yawns from the slow-moving scene outside had been zapped out of existence. (An upbeat opening set from Brazilian groovers Tagua Tagua certainly helped.) All eyes and ears were locked into the fire breathing from the stage. That’s the beauty of a White Denim show: no matter the venue, the crowd, the weather outside—when the band hits, you get the feeling you’re privy to underground rock magic bubbling up from some unknown basement.

But it’s been a long time since the basement, and White Denim has nothing left to prove. Petralli seems to have traded the stern bravado of days gone by for the wisdom of the player-coach: encouraging teammates to step out, leaving room for levity (a zipping kazoo solo on “Come Back” was a fun surprise), but still ruling with an iron fist (his Gibson SG) when duty calls.

From the fond and amused looks the musicians shared between them—during Michael Hunter’s synth-sational outro solo on “Sky Beaming”; Cat Clemons’ slide guitar theatrics on “River to Consider”; or Matt Young’s polyrhythmic gauntlet on “Anvil Everything”—it was clear that they were playing for each other as much as anyone else. Besides, it’s hard to have a bad time watching Cat Clemons shred guitar with his ear-to-ear perma-smile.

It was from that space of mutual adulation that the band descended into a deep pocket of psych improv. Though this pocket followed the contours of 2019 Side Effects cut, “NY Money,” with Petralli looping that melody, he soon turned to a steel drum at the front of the stage amid formless pangs from the band. Young peppered in some kind of jangly percussion bushel then turned to sharp cracks in time with Dan Hyman’s bassline; Clemons and Hunter floated in that liminal space, too, before a return to Earth and a smooth segue to the rollicking “Bess St.”

Lest we focus too much on technical prowess and instrumental acrobatics, we shan’t overlook the great power of Petralli’s songwriting. The nearly two-hour set in Allentown touched on gems from every era of the band’s history. Classics like “Street Joy” with its “I don’t differentiate we from they” pondering and the troubadour tour of Texas, “Corsicana Lemonade,” were mixed in with the canon’s newest additions. Each is finding a comfortable home in ever-evolving White Denim setlists, from the bouncy cool-down “Second Dimension”; the happy-go-lucky “Hand Out Giving” with its musing, “I know who to call if I stumble and fall, commit a criminal act or two”; and the brooding “Ashley Goudeau,” from the 2023 collab record with Raze Regal.

The White Denim of 2025 tours the U.S. and points beyond in full celebration of the immense catalog they have built. It’s largely Petralli’s handiwork. But, this formation of the band—with Clemons, Hunter, Young, plus Hyman often filling the shoes of longtime bassist Steve Terebecki—has been making that catalog their own for about four years now. Their nightly flourishes make each show unique. It adds up to what rightfully could be argued is White Denim’s deepest, most impactful era.

And, if there was any doubt, the quintet sent the eager listeners of Archer Music Hall off with a signature smoker. “Had 2 Know (Personal),” an iconic entry among White Denim’s riff rock rolodex, gave way to Petralli’s rapping on “Fine Slime.” That closing “Fine Slime” jam exploded from the bandstand with an animal tenacity that can’t quite be captured on record. It was that pure ferociousness, cooked up by five individuals in beautiful synchronicity, that stayed fresh on the mind as the crowd returned to those Allentown streets.

In an age of technocratic supremacy, when hungry bots gnaw at the edges of mankind’s sacred artistry, this scintillating performance felt like an act of rebellion—a call to arms, as it were. But instead of the drums of war tip-tapped by those early Allentown militias, we were called to follow the drums, guitars, pianos, flutes, and kazoos of rock n’ roll, and join the fight for humanity’s living spirit.
