In New York City, you can hear the beginnings of a post-pandemic world as much as you can see them. At Manhattan's Javits Center, one of the busiest convention centers in the country in pre-pandemic times, roughly 9,000 New Yorkers shuffle through every day to receive their Covid-19 vaccines. Thanks to Sing for Hope, the nonprofit arts advocacy group known for its colorful public pianos spread across the city, you can also be serenaded while receiving your vaccine. Through its daily performances inside the Javits Center, the organization helps tackle the dual problem of "rampant artist unemployment" and anxiety surrounding getting a Covid-19 vaccine, Monica Yunus, co-founder of Sing for Hope, told CNN.
