Romantic mariachi crooner Pepe Aguilar brings his elegant rancheras for two shows at the Universal Amphitheatre. The native of Zacatecas, Mexico, and son of singers Antonio Aguilar and Flor Silvestre (a top musical rodeo act of their day) has been performing onstage since he was 4. On his 10 solo albums, including his recent Grammy-winning “Por Una Mujer Bonita,” the honey-toned singer has developed a sophisticated and mature approach to Mexican love songs.

7:30 pm: Movies

Ten underground films from the ‘60s screen over eight days as part of the UCLA Film and Television Archive’s series “From the Factory: Andy Warhol’s Films.” Warhol, a pioneer of Pop Art who became an iconic figure with his silver-white hair, dark glasses and leather jacket, shot hundreds of hours of film in and around his Manhattan loft (the Factory) between 1963 and 1968, but much of it has been unavailable since Warhol withdrew them from circulation in 1972. The Museum of Modern Art in New York preserved these early films, some of which have never been screened in L.A. Saturday’s opening bill is the 1963 short “Haircut (No. 1)” and 1967’s “Bike Boy,” a “sexploitation” feature made with Paul Morrissey that follows a real motorcycle gang member in a series of encounters with a variety of Warhol “superstars.”

* “From the Factory: Andy Warhol’s Films,” UCLA, Melnitz Hall, James Bridges Theater, near the intersection of Sunset Boulevard and Hilgard Avenue, Westwood. “Haircut (No. 1)” and “Bike Boy,” Saturday, 7:30 p.m. “The Velvet Underground and Nico” and “Lupe,” Sunday, 7 p.m. “Harlot” and “Camp,” Wednesday, 7:30 p.m. “Kitchen” and “I, a Man,” Aug. 10, 7:30 p.m. “Screen Test #2” and “The Loves of Ondine,” Aug. 11, 7:30 p.m. $5 to $7.

The swing explosion may have lost its zing, but Brian Setzer is still jumpin’, jivin’ and wailin’. The former Stray Cats frontman and leader of the Brian Setzer Orchestra says he wasn’t planning to tour but was lured to the road when several impromptu shows in November turned out so well. The new lineup is called the “Brian Setzer ’68 Comeback Special” (yes, it’s a nod to Elvis Presley’s famed gig) and features old Setzer cohorts Bernie Dresel on drums and slap-bassist Mark W. Winchester.
