Underoath Announce ‘Define The Great Line’ 20th Anniversary Tour With August Burns Red, Atreyu, Emery & As Cities Burn

Underoath will spend the closing months of 2026 celebrating one of the most important releases in their catalog. The Florida post-hardcore veterans have officially unveiled a North American tour commemorating the 20th anniversary of their landmark 2006 album, ‘Define The Great Line’.

The extensive run launches in November and stretches through mid-December, culminating with a hometown performance in Tampa, FL just before the holiday season. Joining the band throughout the trek will be August Burns Red and Atreyu, while As Cities Burn and Emery will rotate in on select dates.

The anniversary outing will see Underoath performing material from the gold-certified record that helped redefine heavy music during the mid-2000s and remains one of the band’s most celebrated releases.

Keyboardist Chris Dudley reflected on the significance of the album and the opportunity to dedicate an entire tour to it:

“What this album has meant to us, and so many others, over the past 20 years is hard to quantify. It gave us permission to be ourselves. It sent us around the world. It gave people the freedom to say (and scream) the things out loud they had buried deep. It will outlive us. We still play these songs on stage 20 years later and get those chills. The opportunity to devote an entire tour to presenting this album in the best way it ever has been, alongside friends we’ve had since before it was released, is going to be bucket list material for us.”

A large portion of the lineup will also appear at August Burns Red’s annual ‘Christmas Burns Red’ event on December 3rd in Lancaster, PA. That show will feature a co-headlining bill from Underoath and August Burns Red, alongside Atreyu, Emery, and one additional artist yet to be announced.
