Charli XCX and Allie X lead a huge roster of pop and dance artists who are banding together to play the Billy Ball on Nov. 30 in support of 21-year-old British musician Billy Clayton, who has been battling an aggressive form of bone cancer, Ewings Sarcoma, for three years.

The show at The Globe Theatre in Los Angeles will also feature sets from Vincint, Dorian Electra, Daya, Leland, Chester Lockhart, Jesse Saint John, Mood Killer, Lulo, Jarian De Marco, Zolita and Phoebe Ryan, among others.

According to a press release announcing the show, Clayton's family intends to use the money raised by the one-night-only event to seek immunotherapy treatment in Germany so Clayton can continue his music career.
