Who choreographed Tango Argentino?

Tango Argentino is a musical stage production about the history and many varieties of Argentine tango. It was created and directed by Hector Orezzoli and Claudio Segovia, and premiered at the Festival d'Automne in Paris in 1983 and on Broadway in New York in 1985. The Mel Howard production became a world-wide success with numerous tours culminating with a Broadway revival in 1999–2000. It set off a world-wide resurgence of tango, both as a social dance and as a musical genre. Tango Argentino recreates on stage the history of tango from its beginnings in 19th-century Buenos Aires through the tango's golden age of the 1940s and 50s up to Piazzolla's tangos. Most of the dancers in the show did their own choreography.

Tango Argentino was a totally unexpected hit. It violated all the rules— It was low budget, used a single set, and showcased slim, athletic professional dancers, such as Nelson Avila, along with middle-aged dancers, such as Verulazo and Elvira Santamaría, all on the same stage. The average age of the cast was 42 years.All this glamour attends a show that even Argentines wouldn't invest in at the outset, a show that made it to Broadway largely by accident, a show that has one set, four accordions (called bandoneons) and a couple of 38-inch waistlines.
