The concert will also be screened live at select AMC Theatres and and Regal Cinema locations in the U.S. If you will be on the move, iHeartRadio, the national audio partner for the event, will also feature the FireAid concert across over 860 radio stations in the U.S., digital platforms, and the iHeartRadio app.

Audiences tuning into the FireAid benefit concert for Los Angeles on Thursday night (Jan. 30) were surprised with an early treat when pop superstar Billie Eilish made a surprise appearance alongside Billie Joe Armstrong and the rest of Green Day for a stirring opening performance.

Dozens of stars will take to the stage in the two-venue extravaganza, which aims to raise money for those affected by this month's fires.
