Gem Duras received his tango training from the stars of the famous show "Forever Tango" most notably the legendary Carlos Gavito with whom he had the opportunity to study extensively for several years, incorporating his technique, elegance and musicality into his own dancing and teaching. Later he studied performance tango with Francisco Forquera in Argentina to become a certified instructor and tango dancer.

Gem co-founded Tango Sueno with Dale Ellison, and during their partnership they have developed a reputation as dynamic Argentine Tango teachers and performers in milonguero, nuevo and performance styles of tango, teaching and performing throughout Connecticut, New York and California. They have traveled to Buenos Aires numerous times to perfect their technique by studying with Gustavo Naveira, Juan Carlos Copes, Osvaldo Zotto, Oscar Mandagaran, Chicho Frumboli, Geraldine Rojas and Susana Miller among others. They have also founded the Connecticut Tango Festival in 2008, creating its 3rd edition in 2010.

Gem recently performed and taught at the Stardust weekend upstate New York, and participated as a performer in the New Year’s Celebration event organized by Akademi Tango, in Ankara-Turkey. He has recently started a collaboration with Valentina Molina; together they taught for the Hartford Argentine Tango Society and have been invited as guest teachers at their tango cruise week.
