“We’re gonna’ bring you some acoustic Texican rock and roll!” Henry Garza yelled into the microphone, peering out at the audience behind shaded sunglasses framed by dark, shoulder-length hair.

Los Lonely Boys had just taken the stage at Harrah’s Lake Tahoe South Shore Room Saturday night, amid the frantic cheers and applause of the excited fans that crammed the venue.

The Texas Chicano-rock band of brothers got right down to business, blasting their screaming fans with the crunchy, opening riffs of “I’m the Man to Beat.” Soulful harmonies from Garza and brother Jojo overlaid bluesy, SRV-esque guitar work that included brief strains of rock classics, “Smooth Criminal,” “Lowrider” and “Smoke on the Water.”

Los Lonely Boys put on a riveting show, exuding electrifying and soulful expression. It was easy to see that each of the brothers Garza his entire body and mind into his music. Henry and Jojo Garza sang individual lines and harmonies with searing intensity, channeling the depth and passion of their heritage. Drummer Ringo Garza’s energy was great fun to watch, frequently shelving his left-hand drumstick and using the free hand to beat out the zesty rhythms on one of a number of congas and other hand-drums within reach.

The band largely played songs from their most recent album, 2011’s “Rockpango,” including “Love in My Veins,” “Smile” and the hauntingly grooving “Road to Nowhere.” The Garzas ended their funky romp “16 Monkeys” with the familiar Batman theme, much to the amusement of the audience. LLB fans were rewarded with some classic material as well, as the band ended its set with 2004’s hit “Heaven.”

The Harrah’s concert marked the second Los Lonely Boys show since returning from a weeklong trip to Japan, where they were somewhat surprised at their reception.

“We just got back from Tokyo, Japan,” Henry Garza told the crowd at Saturday’s show. “And everybody at the show was from America.”

While an authentic Japanese fan base may elude the Garzas for the moment, there’s no question that there are plenty of devoted Los Lonely Boys fans stateside.
