David Guetta just brought New York City's largest dance party from the Top of the Rock directly into fans' homes through his #UnitedAtHomeNYC livestream. In an a collaborative effort with Mayor Bill de Blasio and First Lady Chirlane McCray, the French DJ spun from the top of 30 Rockefeller Center to help raise money for the Mayor's Fund to Advance New York City and other COVID-19 relief charities.
