The Maine will headline both nights of their hometown festival at Mesa Amphitheatre on January 15–16, celebrating 20 years as a band alongside longtime friends, Arizona favorites, and a new generation of alternative artists.
The Maine are bringing 8123 Fest back to Arizona in January, and the lineup for the festival's fifth installment is officially here. Set for January 15–16, 2027, at Mesa Amphitheatre, the two-day event will celebrate the Tempe band's 20th anniversary with performances from The Band Camino, Andrew McMahon and the Strings Attached Quartet, The Academy Is…, Beach Weather, The Aces, The Summer Set, and more.
The Maine will headline both nights, performing two entirely different sets with no repeated songs. With nearly two decades of releases behind them, the format gives the band an opportunity to revisit different periods of their career, from their early pop-rock material to the music that has shaped their more recent years.
Friday's lineup features The Band Camino, Beach Weather, The Aces, In Color, Franklin Jonas and the Byzantines, and Moody Joody alongside The Maine. Saturday will lean further into the band's alternative-rock roots, with Andrew McMahon and the Strings Attached Quartet, The Academy Is…, The Summer Set, Nick Santino, Broadside, and Phoenix singer-songwriter Sydney Sprague.
The lineup brings together several generations of alternative music, including artists whose careers developed alongside The Maine during the late-2000s pop-punk and emo scene. The Academy Is… and Andrew McMahon are particularly familiar names from that era, while The Band Camino, Beach Weather, and The Aces represent some of the more contemporary sounds that have found an audience within the same community.
Arizona artists also have a place throughout the weekend. The Summer Set, who emerged from the Valley's pop-rock scene around the same time as The Maine, will return for Saturday's performances, while Sydney Sprague joins the lineup with her own brand of indie rock.
For The Maine, the anniversary comes during an active period for the band. Their latest album, Joy Next Door, continues the group's evolution beyond the sound of their 2008 debut, Can't Stop Won't Stop. Written and recorded sequentially, the record follows a connected musical narrative and introduces another chapter in the band's catalog.
That catalog has changed considerably since the group's early years, moving through pop-rock, alternative, indie, and more expansive production across nine studio albums. Despite those changes, The Maine have maintained an independent approach to their music and developed a dedicated audience through their 8123 community.

8123 Fest has become one of the most recognizable parts of that relationship. Rather than organizing a conventional touring festival, The Maine have continued to bring fans to their hometown, where the event has grown into a gathering that extends beyond the performances themselves.
“8123 Fest is all about the people that have created a family around our band,” drummer Pat Kirch said in the announcement. “Fans from all around the world getting together in our hometown, all celebrating 20 years of something that is much bigger than music.”
The festival will extend across several days, beginning Thursday, January 14, with an 8123 pop-up shop and kickoff party. Both festival nights will be followed by emo afterparties, while Sunday will feature another pop-up shop and a sendoff party.
The weekend concludes Monday, January 18, with 8123 Impact Day, featuring charity and community activities throughout Arizona. Additional side shows and special events are also expected to be announced.
The Maine's decision to perform two completely different headlining sets adds another reason for longtime fans to attend both days. With songs spanning their early releases, fan favorites from albums like Lovely Little Lonely and You Are OK, and newer material from Joy Next Door, the anniversary weekend leaves plenty of possibilities for what the band might bring to the stage.
Twenty years after forming in Tempe, The Maine will return to Mesa Amphitheatre surrounded by artists from different chapters of their career and a fanbase that has followed them through those changes. For a festival built around the band's hometown and the community that grew alongside it, the 2027 edition brings those two histories together.
