In a festival season with no music festivals, Global Citizen has been working to bring pop's biggest acts into a shared virtual space.

Last weekend, the international aid group with ties to the United Nations presented One World: Together At Home, an all-star special featuring the likes of Lady Gaga, Taylor Swift, Billie Eilish, Jennifer Lopez, Paul McCartney, Elton John and the Rolling Stones – each of whom performed from wherever they're sheltering in place amid the Covid-19 pandemic that's brought the live music industry (and so much more) to a standstill.
