If you missed the recent Tejano Conjunto Festival, don’t despair — two of this year’s hottest acts will grace the Arneson River Theater stage in a “tribute to the kings of accordion.” It’s a fitting homage, as Juanito Castillo and Dwayne Verheyden are exemplary protégés of their respective masters. Castillo, a young San Antonio native, hooked up with legendary Steve “Esteban” Jordan and absorbed the late Jimi Hendrix of the accordion’s magical, genre-pushing style. Verheyden, a baby-faced 22-year-old from the Netherlands, looks to Flaco Jiménez for his precise conjunto mastery. Both will play backed by a band comprised of notable players like Gabriel Zavala, host of KSAT’s Tejano y Más program (and a member of Lush and Stefani Montiel’s band), and Jaime Villanueva, a longtime guitarist for Jordan. The Michael Guerra Band opens. Free, 7pm Tuesday, Arneson River Theater, 418 Villita, (210) 717-5096, arnesonrivertheater.com.
