Metallica, Biden and Mariah Carey come together against poverty

New York: Metallica and Mariah Carey on Saturday led an A-list of musicians, and President Joe Biden made a surprise video appearance, as the Global Citizen Festival sought to mobilize action against poverty and climate change.

Marking its 10th year, the six-hour festival brought thousands to New York´s Central Park and featured a sister show in Ghana´s capital Accra, where performers included American R&B great Usher and British grime icon Stormzy.

Global Citizen awards tickets to fans in exchange for their commitment to take action to eradicate extreme poverty -- such as contacting elected representatives to encourage foreign aid -- and coincides with the annual UN General Assembly in hopes of raising pressure on world leaders.

"We´re inspired and grateful for all the work you´ve done and want you to know -- your fight is our fight," First Lady Jill Biden said in a video appearance next to her husband.

President Biden -- along with top Senate and House Democrats Chuck Schumer and Nancy Pelosi, who both appeared in person -- highlighted a new climate package that is the most far-reaching legislation ever in the United States to spur clean energy.

But Prime Minister Mia Amor Mottley of Barbados warned that action against climate change cannot come quickly enough for islands such as hers.

"Yes, my friends, our time is running out," she said.

Thrash metal legends Metallica got the crowd headbanging with eight songs including a version of "Nothing Else Matters" featuring vocalist Mickey Guyton, who has been outspoken about her experiences as one of the most prominent Black women in country music.

Mariah Carey was introduced by leading ballerina Misty Copeland, who called the singer with her famed vocal range an inspiration, and was accompanied by a choreographed dance for her classic song "Hero."

Other performers included Maneskin, the new-generation Italian glam rockers who put on an energetic set, Spanish pop star Rosalia, and the Jonas Brothers, with Nick Jonas´ wife, Indian screen star Priyanka Chopra, serving as master of ceremonies. (AFP)
