Nuevofest. This annual free fest aims to present "the new music of Latin America" (though electronic duo Delaporte hails all the way from Spain). There are lots of intriguing acts among the seven performing on the six-hour show, including five-piece San Antonio dance band Femina-X. The likely highlight, however, is Orquestra Akokan, the old-school Cuban big band led by Jose "Pepito" Gomez, which has just released a terrific self-titled record on the Daptone label. Sunday at 4 at the World Cafe Live and video streaming at

Queen of Jeans, "U R My Guy." The South Philly rock quartet fronted by singer Miriam Devora puts a spin on a scene from the 1999 teen rom-com 10 Things I Hate About You in the video for this choice nugget from their album Dig Yourself. Instead of Heath Ledger serenading Julia Stiles with Frankie Valli's "Can't Take My Eyes Off of You" from the bleachers of a high school football stadium, though, it's Devora and her bandmates singing to QoJ's drummer, Patrick Wall. The band opens for Japandroids at Boot & Saddle on July 27.

La Santa Cecilia. The terrific Los Angeles-based Mexican American dance band fronted by Marisol "Le Marisoul" Hernandez mixes cumbia, mariachi and norteño music, among other styles, with rock. The group's  2013 Grammy-winning album Treinta Dias featured a collaboration with Elvis Costello on "Losing Game," and the band is touring behind last year's lively Ama y Vivir. Tuesday at the Foundry.
