Phoebe Bridgers performed a cover of Nirvana's "Lithium" during a BBC Radio 1 Live Lounge session that aired on Wednesday 19 August 2026. The set also featured her own songs "Bobby" and "Lost Boys" from her latest album, Lost Weekend, marking their first widely available live performances.

The session appears to have been recorded before Bridgers developed appendicitis, an illness that has since forced her to postpone the remaining UK shows scheduled for this week. She is expected to have ample time to reschedule those intimate dates before her larger "The Lost Tour" begins next month, and the full performance had not yet been uploaded to YouTube at the time of publication, though audio clips circulated online.
