All Things Go Music Festival: Mitski, Ethel Cain & Rainbow Kitten Surprise – Friday at Merriweather Post Pavilion

All Things Go Music Festival 2026

All Things Go Music Festival – Friday, September 25th at Merriweather Post Pavilion in Columbia, MD. Doors open at 3pm, with music starting at 3:35pm. This special show will feature three main stage performances by Mitski, Ethel Cain and Rainbow Kitten Surprise. The festival’s full lineup will also be performing on hand, including additional main stage performances by Magdalena Bay and Slayyyter and many more. 

Mitski

The highly-acclaimed indie rock and art pop artist Mitski is known for her soulful, often intense and equally beautiful performances. See her perform her most popular songs “My Love Mine All Mine,” “Your Best American Girl,” and “Washing Machine Heart” and more as she returns to the ATG Festival this Friday live on stage.

The ambitious and artistic singer-songwriter has just put out her newest release Nothing’s About to Happen to Me (2026) which is a very unique concept album. The release follows her 2023 release The Land Is Inhospitable and So Are We which was a full symphony with a full choir. Known for her raw and honest songwriting the Japanese-American singer-songwriter writes songs of identity, of isolation and of the many social struggles of today. Her Oscar nominated song for Best Original Song for “This Is a Life” from the hit film Everything Everywhere All at Once was also her first appearance on the Billboard Hot 100 chart with her breakthrough song “My Love Mine All Mine.” 

Ethel Cain

Ethel Cain is bringing her Ambient Southen Gothic Visuals to the All Things Go Music Festival this Fall. “American Teenager,” “Crush,” and “Sun Bleached Flies” are just a few of the fan favorites that the singer has been performing live of late.

The singer’s first album, Preacher’s Daughter, is a concept album that houses some of the singer’s biggest songs to date. The epic rock songs are haunted by the folk of deserted landscapes and the singer herself has struggled with themes of Americana, faith, and her own personal struggles. Her vinyl re-release of the album got her first album into the Billboard 200’s top 10 and made her the first openly transgender singer to reach the mark. 

Rainbow Kitten Surprise

Known for performing songs such as “It’s Called: Freefall”, “Cocaine Jesus”, “Devil Like Me”, and “Painkillers”, Rainbow Kitten Surprise brings a unique style of alternative indie rock to the table that is unlike just about any other group currently in existence.

This boisterous and incredibly energetic group of performers have come a very long way since the day that lead vocalist, Darrick “Bozzy” Love, formed the group back in 2013 in the small town of Boone, North Carolina. In 2016, the band will be touring in support of their recently released album, Bones, which was dropped in September of last year and is the follow-up to their 2014 release, Love Hate Music Box. Their 2015 release, Cold as Wolves, was a huge success and was produced by Grammy Award winning producer, Jay Joyce, and the group has continued to receive huge amounts of success as of late with over 2 billion streams across the globe.
