    Chinese pianist Lang Lang will join in a star-studded cast of celebrities for One World: Together at Home, a televised and online-streamed global concert honoring and supporting front-line healthcare workers amid the coronavirus pandemic.

The show is put on with support of the World Health Organization and the international advocacy organization Global Citizen.

"It is one of the most important experiences in my life. It has made me a part of music history. I feel very honored to do what I can do for fighting the virus," says the pianist. "We both know music is without borders, so I do think good music can unite the world and give people power."

The two-hour-long virtual concert will be broadcast at 8 pm US Eastern Time on April 18 on multiple TV networks and online streaming platforms, with the participation of a lineup of artists including Paul McCartney, Andrea Bocelli, Stevie Wonder, Billie Eilish and many other stars.

One World: Together At Home will be hosted by Jimmy Fallon of The Tonight Show, Jimmy Kimmel of Jimmy Kimmel Live and Stephen Colbert of The Late Show with Stephen Colbert. Friends from Sesame Street will also be on hand to help unify and inspire people around the world to take meaningful actions that increase support for the global COVID-19 response.

The digital stream will be available on social media platforms, including Alibaba, YouTube, Facebook, Instagram and Tencent Music Entertainment Group.

"We are grateful to the private sectors who have listened to the public's call for action and come together to support the global response to COVID-19. This pandemic is too large for governments to tackle alone," said Hugh Evans, co-founder and CEO of Global Citizen. "We are also incredibly grateful for the continued support from the artist community to make One World: Together At Home a moment of global unity. Our hope for the special is that everyone will come away believing that we, as a shared humanity, can emerge from this moment forever grateful for the work of doctors, nurses, teachers, grocery store workers and all those who are the backbone of our communities."
