Knickers in a twist

Wardrobe malfunction, indeed. “The Underpants” is Steve Martin’s adaptation of a 1910 comedy by German playwright Carl Sternheim, in which the young wife of a petty bureaucrat becomes an object of widespread desire after dropping her knickers (perhaps accidentally, perhaps not) during the era’s Super Bowl equivalent, a royal parade. The nature of desire and the social need to keep up a proper front are among themes undergirding the comical doings between the wife, her outraged husband and the several new men in her life.

“The Underpants,” Laguna Playhouse, 606 Laguna Canyon Road, Laguna Beach. 8 p.m. Tuesdays through Fridays, 2 and 8 p.m. Saturdays, 2 and 7 p.m. Sundays (2 p.m. only on May 1). $45-$54. (949) 497-2787, www.lagunaplayhouse.com.

* Ends May 1.

Fitting his nature

The latest exhibition at the MAK Center for Art and Architecture explores Austrian architect Gunther Domenig’s work and creative process through drawings, models, texts and photographs. “Structures That Fit My Nature” focuses on two recent projects by Domenig, including the Nuremberg Documentation Center, a historical archive of Nazi Germany that was once the site of the Nazi Party’s rally grounds; and the personal space of the Steinhaus, Domenig’s family property in Austria.

“Gunther Domenig: Structures That Fit My Nature,” MAK Center for Art and Architecture, Schindler House, 835 N. Kings Road, West Hollywood. Opens Thursday. $7; 12 and younger, free. (323) 651-1510.

* Hours: 11 a.m. to 6 p.m. Wednesdays through Sundays. Ends June 26.

FRIDAY

U2 ticket challenge

The “sold out” sign slapped on a big concert can be a deterrent or a challenge, depending on the levels of your devotion and disposable income. And in Southern California -- the hotbed of the ticket-broker brotherhood and the land where who you know is as important as who you are -- getting into U2’s Arrowhead Pond and Staples Center shows might not be such an insurmountable task.

U2, with the Kings of Leon, Arrowhead Pond, 2695 E. Katella Ave., Anaheim, 7:30 p.m. Friday and Saturday. Sold out. (714) 704-2500.

* Staples Center, 1111 S. Figueroa St., L.A., Wednesday and next Thursday, 8 p.m. (213) 742-7340.

Thunder, lightning

Cambodian dancer-choreographer Sophiline Cheam Shapiro moved to the U.S. in 1981 and knows about culture shock from personal experience. “I had always thought that Cambodia was my home,” she told a Times reporter in 2003. “Then the moment I stepped on the plane [to go back], I realized, no, here is my home too.” Her life journey has now become the dance drama “Season of Migration,” performed by the Dance and Music Ensembles of the Royal University of Fine Arts, Phnom Penh. Completing the program: “Ream Eyso and Moni Mekhala,” an ancient Cambodian duet teaming the god of thunder and the goddess of lighting.

Dance and Music Ensembles of the Royal University of Fine Arts, Phnom Penh, in “Seasons of Migration.” Carpenter Performing Arts Center, 6200 Atherton St., Long Beach. 8 p.m. Friday. $30 to $38. (562) 985-7000.

* Also 8 p.m. Saturday.

The Beat’s birthday

Without committing to one side or the other, Los Angeles radio station 100.3 the Beat has prospered by maintaining a neat balance of hip-hop and R&B;, encouraging the kind of cross-pollination that’s enriched both genres. The Beat’s gone on for 15 years now, and the station’s birthday lineup at the Universal Amphitheatre includes Warren G, 112, Xscape and Marques Houston.

100.3 the Beat Birthday Bash, Universal Amphitheatre,

100 Universal Plaza, North Hollywood, Friday, 8:15 p.m.

$15 to $125. (818) 622-4440.

SATURDAY

Norman recital

Considered by many an ideal recitalist, soprano Jessye Norman will sing a program ranging from Purcell to American spirituals as part of the UCLA Live series. She will also sing a song cycle by Richard Danielpour to texts by Toni Morrison. This may be a down payment on Danielpour’s new opera “Margaret Garner,” with a libretto by Morrison, in which Norman will sing at the Detroit Opera House in May. Mark Markham will be her accompanist.

Soprano Jessye Norman, Royce Hall, UCLA, Westwood. 8 p.m. Saturday. $65 to $112. (310) 825-2101, www.uclalive.org.
