Cowboys Dancehall might appropriately be redubbed Vaqueros Salón de Baile for this stacked Tejano bill. For all the KXTN radio faithful, Janie’s Record Shop regulars and the new crop of Tejano-phile youngsters searching for authentic cultural experience, this show is certainly not to be missed. At the top of the bill, Ramón Ayala (El Rey del Acordeón) will treat showgoers to his signature, Grammy-winning amalgamation of the norteño, conjunto and Tejano styles. As gifted a songwriter as he is player and singer, Ayala, with his electrified but nonetheless traditionally rooted music, is a true giant as an international purveyor of Mexican/Texican culture. Ayala, who believe it or not has been at it since the mid-1960s, is supported on this bill by fellow Tejano pioneer David Lee Garza (y Los Musicales) and conjunto outfit Los DesperadoZ. Órale vaqueros. $20-$50, 7pm Thu, Sept. 1, Cowboys Dancehall, 3030 NE Loop 410, (210) 646-9378, cowboysdancehall.com/san-antonio.
