Carlos Gardel (born Charles Romuald Gardès; 11 December 1890 – 24 June 1935) was a French Argentine singer, songwriter, composer and actor, and the most prominent figure in the history of tango. Gardel's baritone voice and the dramatic phrasing of his lyrics made miniature masterpieces of his hundreds of three-minute tango recordings. Together with lyricist and long-time collaborator Alfredo Le Pera, Gardel wrote several classic tangos.

Gardel died in an airplane crash at the height of his career, becoming an archetypal tragic hero mourned throughout Latin America. For many, Gardel embodies the soul of the tango style. He is commonly referred to as "Carlitos", "El Zorzal" (The [Song] Thrush), "The King of Tango", "El Mago" (The Wizard), "El Morocho del Abasto" (The Brunette boy from Abasto), and ironically "El Mudo" (The Mute).
