Folklife News & Events: 2019 NEA National Heritage Fellows: Las Tesoros de San Antonio

Please Join us for our next Homegrown Concert:

2019 NEA National Heritage Fellows: Las Tesoros de San Antonio: Tejano Singers from San Antonio, TX

Beatriz "La Paloma del Norte" Llamas
Blanquita "Blanca Rosa" Rodríguez

Wednesday, September 18, 2019
Coolidge Auditorium, Ground Floor
Thomas Jefferson Building
The Library of Congress

A conversation with two NEA fellows, accompanied by music from Mariachi Esperanza: Henry Gomez (Director), virhuela, Moises Perez, trumpet, Jose Luis Vaca, violin, and Rafael Aguirre, guitarron

Las Tesoros de San Antonio are a group of elder women performers who teamed up to preserve Mexican and bicultural musical expressions through their singing and storytelling. Janet “Perla Tapatia” Cortez, Beatriz “La Paloma del Norte” Llamas, Blanquita “Blanca Rosa” Rodríguez, and Rita “La Calandria” Vidaurri each had impressive singing careers that soared both locally and internationally from the 1940s to the1960s before tapering off in later years. Through the Esperanza Peace & Justice Center in San Antonio, these women reemerged and teamed up as the group Las Tesoros in the 2000s. Although Janet “Perla Tapatia” Cortez and Rita “La Calandria” Vidaurri passed away in recent years, Llamas and Rodríguez continue to perform and maintain the legacy of the group.

All four women grew up in the West Side of San Antonio, Texas. Each singer, with her personal style and grace, forms part of this unique ensemble that represents the important sound of the Mexico/Texas border. They were all inspired by and connected to many other important Tejana singers, including the great Lydia Mendoza (1982 NEA National Heritage Fellow) and the internationally renowned Eva Garza.

Folklife News & Events: Tuareg Music and Song from Niger September 19 Noon

Homegrown Concerts from the American Folklife Center of the Library of Congress

Les Filles de Illighadad
Tuareg Music and Song from Niger 


THURSDAY, SEPTEMBER 19, 2019, 12:00 PM, No Tickets Required
Coolidge Auditorium, Thomas Jefferson Building


Fatou Seidi Ghali, lead vocalist and guitarist of Les Filles de Illighadad, is one of the only Tuareg female guitarists in Niger. Sneaking away with her older brother's guitar, she taught herself to play. While Fatou's role as the first female Tuareg guitarist is groundbreaking, it is just as interesting for her musical direction. In Tuareg society, woman have traditionally been musicians, but not guitarists. They have been deeply involved with tende, a form of music centered on a drum traditionally made out of a mortar and pestles. Tende rhythms also deeply informed the development of Tuareg guitar music, which is mostly the province of men. In a place where gender norms have created these two divergent musics, Fatou and Les Filles de Illighadad are reasserting the role of tende in Tuareg guitar. In lieu of the djembe or the drum kit, so popular in contemporary Tuareg rock bands, Les Filles de Illighadad incorporate the traditional drum and the pounding calabash, half buried in water. They are thus reclaiming the importance of this forgotten inspiration of Tuareg guitar and asserting the power of women to innovate using the roots of traditional Tuareg music.

Fatou Seidi Ghali, Alamnou Akirwini, Fitimata Ahmadelher, and Abdoulay Madassane Alkika are from Illighadad, a secluded commune in central Niger, far off in the scrubland deserts at the edge of the Sahara. The village is only accessible via a grueling drive through the open desert and there is little infrastructure, no electricity, and no running water. But what the nomadic zone lacks in material wealth it makes up for deep and strong identity and tradition. The surrounding countryside supports hundreds of pastoral families, living with and among their herds, as their families have done for centuries.

Message from Bihar: ‘Finished’ netas can win

There is one big message from the recent by-elections that comes ringing in from Bihar. It has tactical implications for the politics that will unfold in the run-up to 2019: hypothetically, if there are any plans afoot to “finish off” another politician (perhaps someone from a neighbouring state) by sending her or him to jail or encircling her or him in corruption and income tax cases, it will only be counter-productive and may end up evoking sympathy for that individual.
