To the uninitiated, tango is just a dance, albeit a dance with an exotic and sensuous allure. To the true tanguero, it is something akin to a religion, attracting the lost, the lonely, and the fanatical with its formal rituals, its sense of belonging, and its intense emotions. Kapka Kassabova first set foot in a tango studio ten years ago and, from that moment, she was hooked. With the pulse of tango thruming through her body and the music filling in her head, she's danced through the night, from Auckland to Edinburgh, from Berlin to Buenos Aires, suffering blisters and heart-break, as well as forging lasting friendships and experiencing all-too-brief moments of dance-floor ecstasy. Here Kapka takes us inside the esoteric night-time world of tango, to tell the story of the dance from its afro roots to its sequined apotheosis in 'show tango', exploring its cultural and emotional pull and enticing us to join her at the milonga.
