Mariah Carey, Jonas Brothers, and Metallica Perform at Global Citizen Festival

Music may be the last vestige of civility in the U.S. -- with each half of the country hating the other half -- and the annual Global Citizen Festival Saturday proved the point.

Mariah Carey, Metallica and the Jonas Brothers hit the stage in NYC's Central Park for a concert that showed everyone can come together, at least for some good tunes.

It's become a tradition -- the 10th this time around -- to underscore how music can make our spirits brighter.

There's also a long play for the event ... to cajole corporate bigwigs to ante up in an effort to end extreme poverty.

The Jo bros went first with songs like "What a Man Gotta Do," "Sucker" and "Only Human." Nick performed "Jealous" and Joe did the honors for "Cake by the Ocean."

Mariah was awesome! The crowd went nuts as she sang "Obsessed," "Honey," "We Belong Together," and, of course, "Hero."

Metallica hit the stage with "Nothing Else Matters," "Creeping Death," "For Whom the Bell Tolls," "Enter Sandman" and "Sad but True."

Charlie Puth got in on the action with “New York State of Mind” and "Left and Right".

President Biden appeared on video to tout the new climate legislation that he signed.
