Lucy Dacus brought her boygenius bandmate Julien Baker on stage during her set at the Outside Lands festival in San Francisco to perform their song "Bullseye" together. The moment offered fans a rare live glimpse of the pair's close creative partnership outside their full band, adding to a run of notable guest appearances at this year's festival.

Dacus invited Baker up during the festival's second day at Golden Gate Park, telling the crowd she wanted her "best friend" to join her, while Baker admitted to feeling nervous before the pair delivered the song from Dacus's 2025 album Forever Is a Feeling. The performance was described as warm and well-received by the audience, and follows other high-profile collaborations at the same event, including Charli XCX joining the Strokes.
