CITY PERFORMANCE HALL OPENERS: On Thursday, we learned that Sarah Jaffe will open City Performance Hall on Sept. 14 with a 7 p.m. concert. But another concert goes down the same day – late night. KXT’s Triple Play will feature a lineup of locals The Relatives, Seryn and a special reunion of Pleasant Grove. Details are still being worked out on the time, ticket prices, etc., but as soon as we hear, we’ll pass ’em along. The Art&Seek crew is touring the new venue in just a bit, so we’ll also report back with any fun facts.

A WORLD PREMIERE: The University of North Texas is presenting the world premiere of The Tall Boy, starring Tandy Cronyn. The show, which runs through Sunday, is adapted from a short story by Kay Boyle. Cronyn worked on the adaptation with UNT director David Hammond and British playwright Simon Bent. In the play, an American matron at a post-WWII camp for displaced persons tells the stories of three boys: a Czech, a Pole and an Italian. Cronyn plays the matron as well as the three boys in the one-woman show. “This story got into my DNA and I knew I had to give it life,” she tells theaterjones.com “I’ve been happy to see all stages of its development.”

THE NO-SHOWS: Yesterday, we passed along news of a big meeting between the Irving City Council and its development partner for the proposed Las Colinas Entertainment Complex. But that meeting didn’t happen as planned after the council members against the project didn’t show up.
