[2] As an original member of the cast, Nelson Avila was an integral part of that Tango Argentino revival.

[9] In 1974, Hector Orezzoli[10] and Claudio Segovia,[citation needed] two Argentine set designers, decided to put together a production about tango using the best dancers in all of Argentina.

Claudio Segovia recounted that he wanted to reflect on the stage the reality of tango life in Buenos Aires, therefore he looked for an authentic mixture of the different types of musicians and dancers, of children, young people and mature people: "Elegí gente que según mi juicio era la más auténtica, la más verdadera, y creo que no me equivoqué."

[1] Nelson and Nélida were dancing and directing the choreography at the famous Michelangelo tango show[11] in San Telmo at the time.

They had already been dancing together in the most prominent shows in Buenos Aires, had appeared together numerous times on television, and had performed internationally.

Nelson, Nélida and the rest of the cast of Tango Argentino boarded an Argentine military transport headed to Paris.

Celebrities took in the show, including Frank Sinatra, Madonna, Brooke Astor, Mikhail Baryshnikov, Helen Gurley Brown, Henry Kissinger and Claus von Bulow.

[1] On tour, Nelson and Nélida danced their solo before the likes of Princess Diana, Jacqueline Kennedy, Ann Miller, Rita Moreno, Mikhail Baryshnikov, Rudolph Nureyev, Burt Reynolds, Kirk Douglas, Dustin Hoffman, Robert De Niro, Liza Minnelli, Katharine Hepburn, and Placido Domingo.

[14] In 2004, Nelson appeared in Luis Bravo's Forever Tango, dancing with Zita González in its production on Broadway, Chicago,[15] Rome,[16][17] Toronto, Philadelphia and Detroit.

The movie starred Raul Julia as a Tango show owner, who returns to Buenos Aires to join his partners after the oppressive government of Argentina has dissolved.

[20] This movie, directed by the prolific Enrique Carreras, is based on a 1941 theatrical comedy by Camilo Darthés and Carlos S.
