KXT LIVE SESSIONS: Singer-songwriter Matt Costa dropped in on the KXT studio recently to record a couple of songs for KXT Live Sessions. He sings “Lullaby” off of his album Mobile Chateau in the video above. If that leaves you wanting more, you can watch him perform a few more of his songs over at kxt.org. And while you’re there, take a listen to some of the other artists who’ve come by the studio.

ART ON THE TRACKS: The DART Green Line is now open, running from Carrollton to Fair Park and on down to southeast Dallas. And all along the line, public art dots the stations. The primary purpose of the art is to make that daily commute go by a little faster. But David Ehrlicher, DART’s chief architect, says there are other pluses. “One of residual benefits is the station is cared for and welcomed, and that may result in less abuse and vandalism,” he tells dallasnews.com. “It promotes a general sense of safety and well-being.” Artists who contributed work include Chong Keun Chu,  Hyun-Ju Chu, Harold Fooshe Clayton, Leticia Huerta, Vicki Meek and James Michael Starr. (If you’ll recall from September, Starr wasn’t entirely pleased with the experience.)

FROM ARLINGTON TO THE DMA: On Sunday, the Dallas Museum of Art opened “Big New Field: Artists in the Cowboys Stadium Art Program.” The show includes work by Olafur Eliasson, Annette Lawrence, Franz Ackermann and other artists. And Gaile Robinson says that the change of venue is eye-opening. “Seeing what the artists created for the vastness of the stadium and then visiting the museum does proffer the intended context; the stadium art is dynamic, the museum pieces more contemplative,” she writes on dfw.com. “The art reflects the venue, because it’s all about location.”
