When Carrie Rodriguez was 22, Chip Taylor (“Wild Thing,” “Angel of the Morning”) crossed her path at South by Southwest, asking the young, violin-playing Berklee grad to tour with him. Soon Rodriguez was belting out twangy songs and fiddling across four collaborative albums with Taylor before venturing out on her solo recording career in 2006. Rodriguez’s fifth studio album, 2016’s acclaimed Lola, intertwined her folk/country/Americana style with Mexican boleros and rancheras. As the Spanglish Lola enchanted widely, Rodriguez planted roots more firmly in Texas, where the great-grandniece of Tejana singer and actor Eva Garza embodies her Ameri-Chicana musical heritage. Rodriguez most recently wrote the songs and lyrics for a musical that became a 2022 off-Broadway hit. ¡Americano! is based on the real-life story of a Mexican American who learns his undocumented status when he heads off to volunteer for the Marines. Back home, Rodriguez hosts her long-running musical melting pot Laboratorio to meld folk art forms. Sunday’s installment intrigues with Latin Grammy-nominated Los Angeles artist Amalia Mondragón, who challenges stereotypes of border life by singing in both a feminine manifestation and a masculine one under the name Tereso Perfecto Contreras. Poet ire’ne lara silva cross-pollinates the experiment.
