BEST BETS: Sunday 8/4

7pm Theater

A senator’s wife finds herself on a life-changing journey as she struggles to reconnect with her unfulfilled dreams in “When Grace Comes In,” a world premiere drama by Heather McDonald, co-produced by La Jolla Playhouse and Seattle Repertory Theatre. Seattle Rep’s artistic director, Sharon Ott, will direct the show.

“When Grace Comes In,” La Jolla Playhouse, La Jolla Village Drive and Torrey Pines Road, La Jolla, 7 p.m. Regular schedule: Tuesdays to Fridays, 8 p.m.; Saturdays, 2 and 8 p.m.; Sundays, 2 and 7 p.m. Ends Sept. 1. $19 to $49. (858) 550-1010.

2pm Dance

Most people would use the word “improvisation” to describe what choreographer Loretta Livingston and composer Robin Cox are performing with their four-member ensembles in the Central Library under the title “Move/Let Us Listen.” But Livingston and Cox aren’t most people, so they call it “live composition,” a manner of working in which the performance space and the performing relationships inspire in-the-moment choices within set choreographic or musical structures. Cox’s score will use marimba, vibes, clarinet and violin, while Livingston’s dances not only will have to work well with those instruments but, in her words, “be shaped for the specific container (the room) and carefully planned to occupy the right amount of time (one hour).” The collaboration went splendidly in “Dances for White Rooms” at Cal State L.A. last year, so hopes are high for this second creative encounter.

Loretta Livingston and Dancers and the Robin Cox Ensemble in “Move/Let Us Listen,” Mark Taper Auditorium, Central Library, 5th and Flower streets, downtown L.A., 2 p.m. $5. (213) 228-7025.

all day Art

Tithu are dolls that play a major role in a Hopi girl’s rite of passage and are believed to be created from the appearance of spirit beings known as katsina. Often incorrectly referred to as “kachina,” these dolls and their depictions are imitated and appropriated for tourist kitsch, commercial advertising, political iconography and fine art. Original tithu from the 19th century and later will be on view in “Katsina/Kachina: Tradition, Appropriation, Innovation,” at UCLA’s Fowler Museum. The exhibition will explore the pervasive presence of katsina and “kachina” on the Southwestern landscape through gallery paintings and sculpture, toys, clothing, non-Hopi copies and souvenirs.

“Katsina/Kachina: Tradition, Appropriation, Innovation,” UCLA Fowler Museum of Cultural History, UCLA campus, Westwood. Wednesdays to Sundays, noon to 5 p.m.; Thursdays, noon to 8 p.m. Adults, $5; seniors, $3; students and visitors 17 and under free. (310) 825-4361.

7:30pm Musical

Emmy-winning actor Eric McCormack revisits his role as professor Harold Hill in a staged concert version of Meredith Willson’s “The Music Man” at the Hollywood Bowl. With conductor John Mauceri, the Hollywood Bowl Orchestra and a star-studded cast including Kristin Chenoweth, Jason Graae, Ruth Williamson and Jeffrey Tambor, this single performance introduces Ben Platt as young Winthrop Paroo. Kay Cole is choreographer and Gordon Hunt the director.

“The Music Man,” Hollywood Bowl, 2301 N. Highland Ave., Hollywood, 7:30 p.m. $3 to $90. (323) 850-2000.

8pm Pop Music

When he’s not tied up with any of several bands he’s associated with, Bay Area musician Jonah Matranga likes to perform on his own as onelinedrawing, equipped only with a guitar and a tape loop-drum machine shaped like Star Wars’ R2D2. The extra technology allows him to give wide-ranging performances that include conventional songs and recitations from his journal to offbeat sonic accompaniment.

onelinedrawing, Troubadour, 9081 Santa Monica Blvd., West Hollywood, 8 p.m. $12.50. (310) 276-6168. Also Monday, 7:30 p.m., at Chain Reaction, 1652 W. Lincoln Ave., Anaheim, $9. (714) 635-6067.
