ARLINGTON -- You don't usually see an opera patron clutching a plush toy.But that was fairly common sight at Dallas Opera's free simulcast of its current production of Puccini's Turandot at Cowboys Stadium on Saturday night, where a surprising number of families enjoyed arias and choruses in a venue where they usually would be cheering for touchdowns and field goals.Saturday's live presentation of Turandot, the fourth of its six performances, was transmitted from the Winspear Opera House in downtown Dallas to the stadium, where it was projected on the facility's enormous video screen, often described as the largest HD television in the world.The quality was excellent, conveying the grandeur of the opera production well in its wide shots and made good choices about when close-ups were needed.But all the strengths and weakness of an opera broadcast are magnified in this awesomely grand format, so there were some tradeoffs.It was wonderful to read the eyes of the singers as they delivered Puccini's impassioned lines. But, being in so close also spoiled some of the tricks of costuming and makeup that operas routinely get away with.The screening vividly revealed such unseen aspects as seams in the set's construction and the tenor sweating (which is certainly nothing out of the ordinary).The sound, however, was far better than one might expect. There was a slight boominess and a bit of echo, but it did little to detract from the performances of Antonello Palombi as Calaf and Lise Lindstrom as the title princess.The power of Puccini's tale of love and tyranny in the Orient came through beautifully in scenes such as Liu's (Hei-Kyung Hong) plaintive aria, "Signore Ascolta," in act one.More than 29,000 potential patrons requested tickets for the free event, the second such simulcast presented by the Dallas Opera.Last April, Mozart's Magic Flute was seen at Cowboys Stadium by a crowd of 15,000. The actual attendance for Saturday's simulcast is expected to be announced today.The audience was more casually dressed, younger and more ethnically diverse than opera crowds at traditional venues. There was an especially large number of children.
