Up close with viral Japanese dance troupe Avantgardey

They are eccentric, energetic, and always in sync. They may look like identical bob-haired dolls, but Avantgardey is a show stopping dance troupe from Osaka that's ready for world domination. In 2023, they won over the judges at "America's Got Talent." Since then, they've gained millions of fans around the world and toured across Asia, including a stop in Hong Kong. At the city's M+ museum of visual culture, CNN's Kristie Lu Stout spends a night at the museum with the dance troupe.
