On Saturday, March 24, hundreds of thousands gathered in Washington D.C. and at satellite rallies all over the country in an attempt to finally rattle America’s gun violence epidemic. Following the mass shooting at Marjory Stoneman Douglas High School on February 14, which left 17 dead, surviving students organized the March for Our Lives event to promote much-needed gun law reform.

The D.C. march, drawing an estimated 800,000 marchers, included bone-chilling moments from student activists who’ve been fielding grotesque and often fabricated character attacks since last month’s tragedy. They recruited some A-list pop names to perform at the event, including Ariana Grande, Miley Cyrus, Common and Andra Day, Demi Lovato, Vic Mensa, Jennifer Hudson, Lin Manuel Miranda and Ben Platt.

The event featured two performances near its conclusion from artists for whom the topic of gun violence resonates on an especially personal level. Hudson, whose mother, brother, and nephew were fatally shot by her brother-in-law in 2008, covered Bob Dylan’s “The Times They Are a-Changin.” And after Emma Gonzalez’s emotional speech, her classmates from the Stoneman Douglas drama club and choir performed “Shine,” a song written by two Stoneman Douglas students—Sawyer Garrity and Andrea Pena—following the February tragedy.
