Because so many offshoot acts orbit Grupo Fantasma, it’s easy to forget Austin’s powerhouse purveyors of salsa, cumbia, merengue y más only play a handful of local dates annually. The funky Latin orchestra and famed Prince collaborators headline a benefit with their San Antonio counterpart, “barrio big band” Bombasta. The fundraiser for disability advocates Easterseals Central Texas also features teen femme trio the Tiarra Girls, alt-Americana crew James Keith & the Moondogs, and Peligrosa party-rocker DJ King Louie.
