The Tango Early 1900s. In the last two decades of the 19th century, the dance known as the tango emerges out of the immigrant culture of Argentina's dockside slums.

The Wango Tango lineup also includes Meghan Trainor, DJ David Guetta, Katseye, Nmixx, Xikers, A20 May and Hearts2Hearts. Five of the nine acts are considered Korean popular music (K-Pop).
