Incendiary and Comeback Kid to Co-Headline Within These Walls Festival 2026

Arizona's largest independent hardcore fest just dropped a lineup that's going to make a lot of people book flights. Within These Walls returns to The Nile Theater in Mesa, AZ on September 19th with Incendiary and Comeback Kid co-headlining, and the supporting roster is absolutely stacked.

Here's the part that really stands out. This will be Incendiary's first time ever playing in the state of Arizona. The Long Island hardcore outfit has been tearing up stages for years, and the fact that they haven't hit AZ yet makes this feel like a genuine event. If you're anywhere in the Southwest, this is the one.

The Full Lineup

Beyond the co-headliners, the bill reads like a wish list for anyone who grew up on hardcore and melodic punk. Set Your Goals, Skycamefalling, I Am The Avalanche, and This Is Hell are all on here, which alone would sell this thing. But the organizers didn't stop there.

The full lineup includes: Incendiary, Comeback Kid, Set Your Goals, Skycamefalling, I Am The Avalanche, B.D.R., Beg For Life, Commoner, Darasuum, Eyes Of Salt, George Moshington, Maldita Gente, Mishap, No Cure, Price Of Life, Sorrower, Stateside, This Is Hell, Time X Heist, and Wristmeetrazor.

That's over 20 bands at a single venue. Honestly, the value on this is ridiculous.

Both Headliners Are Riding Momentum

Incendiary just dropped Product Of New York back in March through Closed Casket Activities. It's a twelve-song compilation that collects their early split 7" releases, the Amongst The Filth debut EP, and some previously unreleased tracks, all remastered by Will Putney. The vinyl LP ships May 15th. It's a great look back at where the band started, and seeing them bring that energy to Arizona for the first time is going to hit different.

Comeback Kid are currently working on their eighth studio album. Vocalist Andrew Neufeld shared a list of working titles for 12 new tracks on his Instagram story recently. This follows their 20th anniversary celebration of Wake The Dead in 2025, which included a full re-recorded version of the album. The new record will be the follow-up to 2022's Heavy Steps. Over the last two decades, the Canadian hardcore band has been one of the most important names in shaping the international punk and hardcore scene, so catching them at a festival like this is a treat.

The Venue

The Nile Theater is a historic 1920s venue in downtown Mesa that's become a real hub for live music in Arizona. It's intimate, it's got character, and for a hardcore fest of this size it's going to be absolutely packed. The venue sits at 105 West Main Street in Mesa. If you've been to previous editions of Within These Walls, you already know the vibes.

The Festival Keeps Growing

Within These Walls has been building something real over the past few years. Last year's edition featured Bane, God's Hate, Bleeding Through, and The Warriors, so the bar was already high. The fact that they've landed Incendiary and Comeback Kid as co-headliners for 2026, along with names like Set Your Goals and Skycamefalling, tells you everything about where this fest is headed. It's earned its reputation as Arizona's largest independent hardcore fest, and this year's roster spans multiple generations of the genre.

Tickets and Details

Tickets go on sale Friday, April 10th at 10:00am MST. I'll be real, with a lineup this deep at a venue this intimate, these are going to move fast. Don't sit on this one.
