Sienna Spiro Makes a Hopeful But Hesitant Debut on ‘Visitor’

Rolling Stone | 03.07.2026 21:00
Sienna Spiro called in a battalion of musicians to set the tone for “He’s Not My Baby, I’m His,” which comes midway into her debut album, Visitor. There are trumpet players and a keyboardist and three different guitarists. Two people are on saxophone and another two on trombone, plus three more on bass, four on cello, and nearly a dozen violinists. There are more of them than there are years Spiro has been alive. But her voice is at the center of it all.
