Rising singer-songwriter Sienna Spiro has withdrawn from her scheduled performances at the All Things Go festival, citing "unforeseen circumstances," according to an Instagram Story posted on 31 August. She had been due to appear at both the Washington, D.C. and New York editions of the festival in September, and her exit removes her from bills featuring artists such as Brandi Carlile, Mitski, MUNA and Zara Larsson.

Spiro gave no further explanation for her withdrawal, and it remains unclear whether a replacement act will be announced for her slots; the festival organisers had not commented at the time of writing. The D.C. leg runs from 25–27 September at Merriweather Post Pavilion, while the New York leg takes place the same weekend at Forest Hills Stadium. The cancellation comes despite a strong year for Spiro, whose single "Die on This Hill" reached No. 20 on the Billboard Hot 100 and whose debut album, Visitor, peaked at No. 9 on the Billboard 200; she is still set to launch her My House world tour in Nashville on 13 October.
