Justin Bieber held a surprise impromptu jam session in Los Angeles's MacArthur Park on 22 September, performing alongside several musicians for a gathering of fans and onlookers. The performance is notable given Bieber's notably limited live schedule since cancelling his Justice World tour in 2023, when he was managing Ramsay-Hunt Syndrome, a condition that caused temporary partial facial paralysis. Although he has made select high-profile appearances—including performances at the Grammy Awards, Coachella Festival and the 2026 FIFA World Cup opening ceremony—no traditional world tour has materialised in support of last year's Swag albums.

The 32-year-old singer played cajón and performed songs including "Let Me Love You," "Speed Demon," "All I Can Take," "Yukon" and "Daisies," whilst interacting warmly with fans, including young children in attendance. Footage shared by fans captured Bieber singing and playing percussion, shaking hands with attendees and offering birthday wishes to a child. The casual outdoor session represented a rare opportunity for admirers to see the artist perform live, despite his reduced touring activity in recent years.
