In the high-stakes “theater” of arena rock, Dan Reynolds was a “titan” of energy—a shirtless, “relentless” force commanding tens of thousands. But by 2015, the frontman of Imagine Dragons was “navigating” a private abyss. Behind the “invincible” stage persona, his body was “betraying” him. At just 21, he had been “sentenced” to a life with Ankylosing Spondylitis (AS)—a rare, “aggressive” autoimmune disease that causes the spine to “auto-fuse” like “melting wax.”
“I was ready to delete the song.”
The “Surgical” Pain of the Evolve Sessions
The creation of the 2017 smash “Believer” wasn’t a “spark” of inspiration; it was a “conflagration” of agony. As the band began recording the Evolve album, Reynolds was in a “dark abyss” of physical suffering. He “recounted” feeling as though someone was “drilling” into his hips and lower back with a “staccato” intensity. The pain was so “debilitating” that he often couldn’t stand, let alone “conquer” a vocal booth.
He was an “80-year-old in a 20-year-old’s body.”
“I was in the darkest place of my life,” Reynolds “admitted.” He nearly “purged” the demos for the track, “convinced” he was too “fragile” to deliver the performance the song demanded. He “recorded” takes while propped up by “pillows” or lying flat on the studio floor, “fighting” the “stiffness” that threatened to “freeze” him in place forever.
The “Jelly” of Resilience: Turning Trauma into Tone
The “pivot” happened when Reynolds stopped “resenting” the “flame” and started “harnessing” it. Alongside producers Mattman & Robin, he “translated” the “drilling” sensation of his flares into the song’s signature, “thumping” percussion.
He “weaponized” his weakness into his “greatest” strength.
-
The Lyrics: “First things first / I’ma say all the words inside my head” was a “manifesto” to stop hiding his “hidden” disease.
-
The “Pain” Motif: The driving, “rhythmic” heartbeat of the song was “designed” to mimic the “pulsing” inflammation of his sacroiliac joints.
-
The “Momoa-esque” Defiance: In the music video, he faced Dolph Lundgren (the “Ivan Drago” of chronic pain), taking “hammering” hits to symbolize his daily “sparring” match with AS.
The “Statistical” Coronation of a Survivor
What Reynolds feared was “too dark” for the public became a “global” phenomenon, “cementing” his place as the “voice” of the chronic pain community.
The data “validated” his “vulnerable” gamble.

The “Heavy-Lifting” Legacy
Today, at age 38, Dan Reynolds is a “monolith” of physical “reconstruction.” He “manages” his AS and ulcerative colitis through a “surgical” regimen of Olympic lifting and a “strict” anti-inflammatory diet, training six days a week to “stave off” the “fusion” of his vertebrae. His campaign, “Monster Pain in the AS,” has “mainstreamed” a disease that was once “invisible.”
He “shook off” the “embarrassment” of his illness to become a “lighthouse.”
“Believer” stands as a “monument” to the songs we almost “delete.” Reynolds “proved” that your “bones” can “fuse,” but your “spirit” can remain “fluid.” He “transformed” the “drilling” in his hips into a “shout” of gratitude, reminding a “shattered” world that while “pain” can “break you down,” it is also the “architect” that “builds you up.”
