Sun., March 10, Mariachi El Bronx

Los Angeles punks the Bronx answered a call for an acoustic performance in 2006 by transforming into newfound Latin alter ego Mariachi El Bronx. (Phone booth optional.) No mere dilettantes, these gringos embraced their second identity with fervor, which is apparent in their energetic stage show. They've released two albums under the persona, the latest one coming two years ago. From trilling horns to the clomping block rhythms and Southwestern guitar swoon, El Bronx inhabits the sound. It furnishes it with an intoxicating mix of styles and tempos—including the stomping squeezebox-driven “Norteño Lights,” the anxious tango of “Poverty's King” and the flamenco delicacy of “Everything Dies.” 2708 J Street, www.mariachielbronx.com.
