One night in 2002, a friend gave Jorge Drexler the chorus to a song and challenged him to write the rest of it using a complex, poetic form known as the "Décima." In this fascinating talk, Drexler examines the blended nature of identity, weaving together the history of the Décima with his own quest to write one. He closes the talk with a performance of the resulting song, "La Milonga del Moro Judío."
