The light show in the window of Neiman Marcus in Dallas.

LIGHTS ALIVE: Pedestrians on Main Street in Dallas are stopping in their tracks in front of Neiman Marcus every weekday between 5:30 and 6:30 p.m. That’s when the curtain draws back on a dark window, and three performers outlined in colored light strips begin dancing. Featuring a slice of Lightwire Theater’s “A Very Electric Christmas,” the show runs through Friday.

The hour-long performance is set to classic holiday tunes and features a toy soldier cavorting with gift-bearing mice. The electroluminescent wires have a surreal effect, rendering the dancers as live cartoon figures who interact with viewers through pantomime.

Neiman’s has presented live shows in its windows before, but this is the first time the retailer has staged an eight-day run.

Situated next to the store entrance, the unusual display was conceived through a partnership with Mendelson Entertainment Group, Lightwire Theater and the AT&T Performing Arts Center, where the company will stage a full performance of “A Very Electric Christmas” on Jan. 1.

Based in New Orleans, Lightwire Theater was a semifinalist on “America’s Got Talent” in 2012 and won TruTv’s “Fake Off” competition in 2014. The company also made it to the finals of the French TV competition, “The Best: Le Meilleur Artiste,” in 2013.
