The Levitt Pavilion crowd swayed and swooned to a tango extravaganza Thursday evening, complete with dance lessons and the Latin beats of Leonardo Suarez Paz and the Cuartetango String Quartet.

Paz is a renowned fourth generation tango artist from Buenos Aires. He was joined by his wife, Olga, a seasoned tango dance instructor, who began the show by guiding a handful of audience members through some tango moves.

The musical portion of the show followed as the quarter took the stage. Nominated for two Grammy Awards in 2012 -- for Best Tango Album and Best Classical Contemporary Composition -- the group offered a new twist on the Golden Age of Tango.

"Tango is fun. You can really let your hair down," said Nanda Greifenberger of Westport, who was relaxing on the Levitt grounds with a friend visiting from California. "I took lessons in the city a long time ago, but don't remember the steps."

John and Charlotte Newcomb of Norwalk were among the couples trying out new dance moves. "We ballroom dance once a week and have danced classic Tango for years," said John. "The instructor tonight is teaching Argentine Tango, which is very different in every aspect."

Leonardo Paz "is tango royalty," said Carleigh Welsh, the pavilion's marketing director.
