Twi-Lite Fun Run The words "fun" and "run" hardly seem compatible in this long, mean season, when merely walking from your front door to your car leaves you sticky, spent and ready for Gatorade. Even so, this evening an estimated 2,500 no-pain-no-gain types will run 5K, no doubt rejoicing with every bead of sweat. At least the day's worst heat will have passed by the time Rockets coach Rudy T. signals the shotgun start. (The race, sponsored by 104 KRBE, benefits his Tomjanovich Foundation.) Register 47 p.m. at the Memorial Park Tennis Center, 1500 Memorial Loop; race begins at 7:30. $15 race fee includes food and beverages at a post-run party and the obligatory fun-run T-shirt.
Dietrich Anjelmurra Wegner The young artist contends that his paintings "are in no way pornographic; on the contrary, as simple and innocent as the nude can be." But the High School for the Performing and Visual Arts disagreed -- perhaps because some of Wegner's simple, innocent young men are not only naked but blindfolded or hooded -- and the graduating senior wasn't allowed to display those paintings on the campus. Instead, he's organized his own exhibit, combining his works with those of three other recent grads: abstract painter Jessica Espinoza and photographers Seth Irwin and Sara McCuistion. Opening reception 6:30-8 p.m., Commerce Street Art Warehouse, 2315 Commerce Street. Call 747-7543 for information.
Guy Clark Long, long ago, during a brief and shining moment when commercial radio played country music that hadn't been lobotomized, Guy Clark made a hit of "L.A. Freeway," a sweetly bitter get-out-of-town song that managed to be both smart and unpretentious, and Jerry Jeff Walker had the good taste to cover it. But the zeitgeist rolled on, and Clark didn't. He stayed in Austin. He didn't slick up, and he didn't dumb down. All these years later, his songs still appeal to people who've been to college, traveled and led emotional lives not fully described by Hallmark cards. Tonight he's touring in support of his new album, Keepers, a collection of old standbys, including "L.A. Freeway," "Desperadoes Waiting for a Train" and "The Last Gunfighter Ballad." Singer/songwriter Darrell Scott opens. 7 and 9:30 p.m. At Rockefeller's, 3620 Washington Ave., 869-8427. $10, $15, $20.
Lustmord In the late '80s, artist Jenny Holzer was everywhere. You remember: She's the one whose aphorisms -- such as "Abuse of power should come as no surprise" -- were chiseled into marble, and glowed in electric signs; she was the star of the Venice Biennale. Now, after a five-year dormant period, she's back with a new show. Lustmord takes its name from a German word for sex murder, and Holzer's sobering installation includes human bones and her trademark LED signs. They blink unsettling texts attributable to a killer, his victim and an observer. A sample: "She fell on the floor in my room. She tried to be clean when she died, but she was not. I see her trail." Opens today; museum hours 10 a.m.-5 p.m. On display through August 17. Contemporary Arts Museum, 5216 Montrose, 284-8250; www.camh.org. Free.
The Hollisters This local band named itself after a moonshiner on the Andy Griffith Show -- thus marking itself as both shamelessly country and hip to pop-cult references. They're louder, faster and harder-rocking than you'd expect, and their deadpan hick shtick is aimed high over the heads of Jeff Foxworthy fans. Even so, they're capable of executing a two-step tune even a purist can love. 10 p.m. The Fabulous Satellite Lounge, 3616 Washington Ave., 869-COOL; www.fabsat.com. $6.
Super Summer Science Dr. I. Wonder juggles a bowling ball, a hammer and a flaming torch, all to define "center of gravity." He spins a bicycle tire to show how a gyroscope works. He spits Ping-Pong balls across great distances, the better to explain ... well, there must be some scientific concept at work, and maybe your kids will remember it long after they've stopped trying the trick at home. Other highlights of the Exxon-sponsored "WonderWeekend" include opportunities to make balloon rockets, craters and (the museum swears it's educational) slime. Activities 10 a.m.-4 p.m. today, and 1-4 p.m. Sunday. Dr. I. Wonder performs at 9:30 a.m., 11 a.m., 12:30 p.m. and 2 p.m. today, and at 12:30 and 2 p.m. Sunday. At the Children's Museum, 1500 Binz, 522-1138. $5; free for children under 2.
