Mainline Music Fest will return for its third year in Atlanta this September, featuring 22 bands across three days at four venues. Tickets, including a limited run of 25 all-weekend passes, are now available for purchase here

This year’s lineup includes some of the city’s greatest up-and-coming acts like Scattrbrain, BAUMS, and MUELAS, along with local vanguards such as CDSM, mallbangs, and Janie Danger. This year’s fest also marks the return of indie post-punk outfit Shepherds, which carved new lanes in Atlanta’s scene before going on an extended break in 2020 due to the coronavirus pandemic.

Founded in 2024, Mainline Music Fest’s values are simple: protect press freedom, support artists, sustain humanity. Inspired by the massive artist boycott against SXSW in 2024 in response to the festival’s ongoing collaborations with defense tech companies like BAE and Raytheon, Mainline’s festival organizers strive to create another access point for musicians, allied workers, and music lovers that is free from corporatization, artist exploitation, and war profiteering.

“No one wants warmongers and corporate heads controlling the music industry, but that’s sadly where we’ve been heading for a long time,” says Mainline’s founder and lead festival organizer and curator Aja Arnold. “We hope this annual music fest is one of many contributions and examples of working class people building worlds in place of what corporate overlords have sold us, whether that’s through Spotify, Live Nation, or Ticketmaster. Our fest is for music lovers by music lovers, handled with the level of intention and care that artists and our communities deserve.”

The fest is being hosted across four venues in different parts of the city, including Star Community Bar and Aisle 5 in Little Five Points, Halfway Crooks Biergarten in Summerhill, and Thinking Man Tavern in Decatur.
