Underoath - Define the Great Line 20th Anniversary Tour
Underoath brings the Define the Great Line 20th Anniversary Tour to Austin City Limits Live at The Moody Theater on December 15, 2026, with August Burns Red joining the lineup. The tour revisits the 2006 album that became one of the defining records of Underoath’s career, pairing a full-album anniversary concept with the intensity of two long-running metalcore bands on the same bill.
Underoath at ACL Live
The Austin show is scheduled for 6:30 PM at ACL Live at The Moody Theater. The theater setting should give the anniversary production room for both the heavier material and the more atmospheric moments that made Define the Great Line such an important record.
August Burns Red adds another major metalcore name to the evening, making this one of Austin’s strongest heavy-music bills of late 2026.
20 Years of Define the Great Line
Released in 2006, Define the Great Line pushed Underoath beyond straightforward metalcore, bringing more atmosphere, dynamics and experimentation into the band’s sound.
The anniversary tour gives fans a chance to hear material from that era in a show built specifically around the album’s legacy.
August Burns Red Joins the Austin Show
August Burns Red appears on the Austin lineup, bringing its own highly technical and aggressive take on metalcore to the night.
Fans who want to catch the full bill should arrive early and check the latest venue timing and entry information before heading to ACL Live.
