Sienna Spiro Cancels All Things Go Performances in New York and D.C.

Sienna Spiro has withdrawn from her scheduled appearances at the 2026 All Things Go festivals in New York and the Washington, D.C., area, with Ethel Cain added to the New York lineup following the change.

Spiro had been scheduled to perform Saturday, September 26, at Forest Hills Stadium in New York and Sunday, September 27, at Merriweather Post Pavilion in Columbia, Maryland.

The English singer-songwriter announced that she would no longer appear at either festival because of unspecified “unforeseen circumstances.”

“Hello everyone, I am so sad to say that I won’t be able to perform at All Things Go this year,” Spiro wrote on social media. “I was so excited for these performances but due to unforeseen circumstances I won’t be able to make it this year.”

She apologized to fans who had planned to attend and said she hoped to see them soon.

Spiro’s All Things Go withdrawal comes after she also pulled out of the Newport Folk Festival earlier this summer. No broader cancellation of her upcoming tour has been announced. Her scheduled headline theater run is currently set to begin in October.

The festival has not announced a direct replacement for Spiro’s Washington-area appearance. In New York, however, Ethel Cain has been added as a co-headliner on Saturday alongside Brandi Carlile.

Cain was already scheduled to perform at the D.C. edition of All Things Go on Friday, September 25, where she shares the top of the bill with Mitski.

The New York festival runs September 25 to 27 at Forest Hills Stadium. Zara Larsson and Lola Young lead Friday’s lineup, while Carlile and Cain now top Saturday. MUNA and Carly Rae Jepsen are among Sunday’s leading acts.

The Washington-area event takes place over the same three days at Merriweather Post Pavilion. Its lineup includes Mitski, Ethel Cain, Hayley Williams, MUNA, Zara Larsson, Brandi Carlile and Lola Young.
