Folklife News & Events: Navajo Dancers Jones Benally Family September 10 Noon

Please us for our next Homegrown Concert:

Jones Benally Family Dancers
Navajo (Diné) traditional dance from Arizona
TUESDAY, SEPTEMBER 10, 2019, 12:00 PM
Coolidge Auditorium, Ground Floor
Thomas Jefferson Building
The Library of Congress


World Champion hoop dancer and traditional healer Jones Benally, his daughter Jeneda, his son Clayson, and his three young grandchildren form the Jones Benally Family Dancers. Navajo dance is a sacred tradition encompassing a wide variety of forms, all of which aim to heal the body, mind, or spirit. When presented outside the Navajo community, these dances are modified for public viewing, but they retain their deep capacity to move hearts and minds. The family sings, chants, plays traditional rhythm instruments, and performs a repertoire of over 20 dances, including traditional forms such as basket dance, eagle dance, feather dance, and corn grinding. They are particularly well known for the hoop dance, in which they evoke traditional figures and shapes using five, nine, a dozen, or many more hoops.

Jones Benally is a respected elder of the Navajo Nation in northeastern Arizona. His skill as a hoop dancer has won him worldwide acclaim and multiple world champion titles as well as the first Heard Museum Hoop Dance Legacy Award. Jones was featured as a singer in the 1993 film Geronimo. He works as a traditional healer, and was among the first traditional medical practitioners to be employed by a "Western" medical facility, where he worked for nearly 20 years. Jones Benally is also recognized by the state of Arizona as an Arizona Indian Living Treasure. Jeneda and Clayson Benally have performed with their father for over three decades, and have also made their mark (along with brother Klee) as the Native American Music Award-winning "alter-Native" punk band Blackfire. The siblings' newest project is the duo Sihasin ("hope"). Jones Benally's grandchildren are the next generation to take up the family legacy of Navajo music and dance.

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.

Folklife News & Events: Botkin Event on African American Dolls and Puppets February 18

African American Dollmaking and Puppetry: Renegotiating Identity, Restoring Community
Various speakers and artists, moderated by Camilla Bryce-Laporte

February 18, 2020, 11:30am-2:00pm
119 First Floor
Thomas Jefferson Building

African American artisans utilize ancient skills and innovative technologies to create dolls and puppets that are both whimsical and starkly serious. Their creations — incorporating clay, textiles, wood, glass, and found objects — embrace the somber reality of African American experiences and optimism for a boundless future. Working alone and in communities these artisans create dolls and puppets that articulate Black beauty, strength, style, spirituality, and truth. Their works, embodying older traditions and innovative vocabularies for storytelling, are designed to amuse, educate, and heal. Dolls of each of 8 makers will be displayed on tables from 11:30-12:00 pm and 1:30 pm-2:00 pm.

Folklorist Camila Bryce-Laporte will present six makers as they discuss their work and the stories behind that work. This will be followed with a question and answer session from 12 noon to 1:30 pm.

This program may deal with sensitive subjects and is aimed at adults rather than children.

Some of the dolls will be for sale through the auspices of the Library of Congress sales shop.
