All Things Go DC is set to return to the Merriweather Post Pavillion this September, marking the festival’s 12th anniversary. Following last week’s announcement that Hayley Williams—performing as “the Hayley Williams Show”—and Mitski would serve as the primary headliners for the three-day event, organizers have now unveiled the full, expansive lineup.

The festival continues to solidify its reputation for curating a diverse and buzzworthy roster, with notable additions including Ethel Cain, Zara Larsson, and Slayyyter. The Friday schedule is set to feature performances from Magdalena Bay, Rico Nasty, Ninajirachi, and comedian Robby Hoffman.

Saturday’s programming brings a heavy-hitting mix of talent, including Muna, She & Him, The Beths, Hemlocke Springs, and Grace Ives. The festival concludes on Sunday with a robust lineup featuring Brandi Carlile, Lola Young, Tinashe, Father John Misty, Wolf Alice, and CMAT.

Regarding “The Hayley Williams Show,” reports indicate that the set will draw from the artist’s extensive solo career rather than focusing solely on her recent work. The performance is expected to lean into the nostalgic energy teased in recent social media posts, which referenced past collaborations such as “Airplanes” and “Stay The Night.”

In addition to the DC festivities, the All Things Go brand is expanding its footprint. The NYC edition will take place at Forest Hills Stadium during the same weekend, while the Toronto edition is scheduled for next month at RBC Ampitheatre, headlined by Kesha and Lorde.
