(Denver-based NCS writer Gonzo enjoyed a glorious couple of nights at the inaugural edition of Flatline Fest on June 13-14, and delivered to us the following enthusiastic report, accompanied by photos made by Jacob Juno.)
For heavy music, the US festival circuit is quietly growing into something that defies conventional logic. Recent years have seen the unlikely resurrection of vaunted gatherings like Milwaukee Metal Fest, while longer-running affairs like Maryland Death Fest and Northwest Terror Fest proved that even a global pandemic wasn’t enough to douse their fires for good. And deep in the wilderness outside Glacier National Park, the Blackfeet Indian Reservation enshrined a new kind of heaviness with the 2025 incarnation of Fire in the Mountains.
Obviously, these events don’t just spawn out of thin air. They’re the collective result of dedicated people putting ungodly amounts of time, energy, and creativity into something they all believe in, often at the expense of their own sanity.
But in the end, these festivals are more than just a few days of bands playing songs. They’re community gatherings where occasions are celebrated, longtime friends meet up, new friends are made, and the best kind of chaotic merriment prevails.
Evidently, nobody knows this better than Denver producer Dave Otero and co-promoter Chelsea Lowe, whose first-ever Flatline Fest at Denver’s Oriental Theater last weekend turned out to be a masterclass in how to throw one hell of a fucking party.
