One of the stories rarely told by rock historians involves the way Chicano culture in the 1950s and ’60s intersected with early rock ’n’ roll and R&B to create a classic hybrid.

Los Angeles historian Ruben Molina documented this movement last year with his book, Chicano Soul: Recordings & History of an American Culture, acknowledging the key role that San Antonio played in the brown-eyed soul story.

Sam’s Burger Joint promoter Jerry Clayworth has taken inspiration not only from Molina’s book but also the spirited Third Coast roots music of Austin’s Larry Lange & His Lonely Knights, and decided to put together The Legends of Chicano Soul show, featuring four of the all-time Chicano soul greats: Dimas Garza, Rudy T. Gonzalez, Charlie Alvarado, and Sonny Ace. All of these legends but Ace continue to perform regularly, and they’ll be ably backed up by Lange and his band (except for Garza, who’ll be supported by The Sequence).

“This is better history to me than looking at the Battle of the Bulge in a textbook,” Clayworth says, and S&F agrees.

This all-ages show is scheduled for Saturday, June 28, at Sam’s (330 E. Grayson). Showtime is 9 p.m. and cover is $10 at the door.
