Three months ago, the name meant nothing outside a handful of Atlanta open mics.
Today, his track "Backseat Sermon" sits at No. 14 on the Billboard Hot 100, and a clip of him performing it in a parking lot has crossed 40 million views on TikTok.
The song itself is deceptively simple — a slow-burn confession over a drum loop that sounds like a heartbeat.
Shot on a phone at 2 a.m., Gunn leans against a busted sedan, singing to nobody in particular while moths circle a streetlight above him.
Fans say it feels like eavesdropping on something private.
That authenticity is the whole brand, and it is already under pressure.
Within a week of the chart jump, Gunn signed with a major label, announced a fall tour, and landed a late-night TV debut.
Others are posting side-by-side clips from his early shows, captioning them with a single word: "before." The backlash got louder after a since-deleted post from a producer claiming Gunn's breakout single was written by a team of four.
Gunn responded in a livestream, playing the song from scratch on an acoustic guitar and shrugging. "Believe what you want," he said. "I was there." The clip has 8 million views.
Rising country artist Delia Vance posted a video implying Gunn lifted his signature vocal run from her 2023 EP.
Both camps are now trading streaming numbers like dueling scoreboards, and neither artist has backed down.
Through it all, Gunn has kept his posting schedule weirdly normal — coffee, his grandmother's porch, a stray cat he has named Biscuit.
Fans read it as proof he has not changed.
Resale prices are already absurd, and a second leg is rumored for spring.
For a guy who was playing to twelve people in June, the speed is dizzying — and the question now is whether the mystique survives the machine.
Our take: Gunn's best asset is that he seems genuinely unbothered by the circus around him.
If that holds, he outlasts the discourse.
Final Thoughts
If it doesn't, we will get a very different, very polished second album — and probably a much less interesting one.
