Nine years ago, Joni Mitchell fans wondered if they might ever hear her perform again, after Mitchell - the Canadian singer-songwriter and icon of the folk movement - had an aneurysm that initially left her unable to speak.

But in recent years she has made a gradual recovery, and in 2022 she surprised the music world with a performance at the Newport Folk Festival. And on Sunday, at age 80, Mitchell is set to perform at the Grammy Awards for the first time. Show organizers offered no details about her appearance, including whether she is expected to play solo or with guests.

Mitchell, who was given a lifetime achievement Grammy in 2002 and has won nine competitive Grammys throughout her career - going back to best folk performance in 1970 for "Clouds" - is up this year for best folk album with "Joni Mitchell at Newport," where she was joined by Brandi Carlile, Wynonna Judd and Marcus Mumford, and sang classics like "Big Yellow Taxi," "Both Sides Now" and even George Gershwin's "Summertime."

The Newport appearance - an unannounced set facilitated by Carlile - sparked Mitchell's first ticketed live performance in more than 20 years. The show, a headlining set at Carlile's Echoes Through the Canyon festival at the Gorge Amphitheater in George, Wash., in June 2023, was a nearly three-hour marathon, and "a resurrection," Lindsay Zoladz wrote in The New York Times. "To hear Mitchell hit certain notes again in that inimitable voice was like glimpsing, in the wild, a magnificent bird long feared to have gone extinct."

Other announced performers at the Grammys this year include Olivia Rodrigo, Billie Eilish, Dua Lipa, Travis Scott and Burna Boy, along with U2, in an appearance from the Sphere in Las Vegas, and Billy Joel, who this week is set to release his first new pop single in nearly 20 years, "Turn the Lights Back On."
