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.

For many, Gardel embodies the soul of the tango style.
