R&B songstress Alicia Keys spoke out about the impact of AIDS in Africa and raised funds for her charity, Keep a Child Alive, at her World AIDS Day concert in New York City’s Times Square, MTV News reports. The concert also featured an appearance by rap superstar Jay-Z.

In between performing fan favorites such as “If I Ain’t Got You” and “Superwoman,” Keys talked about her 2002 trip to Africa and the influence it had on her life. The crooner also announced a new contest, which will give some fans an opportunity to accompany Keys on her next visit to the continent.

To be entered into the competition, audience members were told to text a number to donate $5 to Keep a Child Alive. Fans may also enter online.

Keys ended the hour-long show by having Jay-Z join her in performing “Empire State of Mind (Part Two),” a piano-driven sequel to the pair’s hit collaboration.
