Folklife News & Events: Klezmer Jam with Howard Ungar and Seth Kibel September 12, 7 pm

Please Join us for an American Folklife Center Summer Music Jam: Klezmer led by Howard Ungar and Seth Kibel

September 12, 2019, 7:00 to 9:00 pm 
Veterans History Project Information & Welcome Center (LJ-G51) 
Thomas Jefferson Building, Library of Congress

The American Folklife Center's series of informal jams to celebrate our living folk traditions, and to bring to life the collections from our vast ethnographic archive continues in 2019. This jam will be led by Howard Ungar and Seth Kibel. So grab your violin, clarinet, trumpet, or other instruments, and come on over to the Library of Congress for the Klezmer Jam.

Seth Kibel is the leader, clarinetist, and composer for The Alexandria Kleztet, an innovative award-winning klezmer band he founded in the Baltimore/Washington area. The band has released four albums that all recieved the Washington Area Music Award for best album upon their release. In addition to his activities with The Kleztet, Seth has fronted a variety of swing and jazz groups, including Bay Jazz Project.

Klezmer trumpeter Howard Ungar founded the DC Klezmer Workshop. Howard has been playing klezmer trumpet since he attended his first KlezKamp in 1999 and has attended many KlezKamp, Yiddish New York, and KlezKanada festivals. He is a founding member of the DC based klezmer band Mrs. Toretsky’s Nightmare, who have played at numerous weddings, bar-mitvahs, and holiday events. You can also hear him playing trumpet with the DC based Machaya Klezmer Band at the Washington Folk Festival and other venues around town. 

This event is co-sponsored by the DC Klezmer Workshop

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: 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: Women Documenting the World September 26 All Day

Please join us for a day-long symposium:

Women Documenting the World
Women as Folklorists, Ethnomusicologists & Fieldworkers
Thursday, September 26, 2019 
9:30 am -5:00 pm
Mary Pickford Theater, James Madison Building, Library of Congress

The American Folklife Center launches its multi-year initiative to highlight, explore, and celebrate the contributions of women as ethnographic fieldworkers and scholars with Women Documenting the World, a day-long program of talks, interviews, and discussions on Thursday, September 26. 

The free event, which is open to the public, calls attention to the role of women in establishing many of the foundational collections that enrich the American Folklife Center archive as well as other ethnographic archives throughout the world. It features presentations by contemporary researchers who are currently engaged in both national and international fieldwork, and includes brief presentations by American Folklife Center staff about important fieldwork collections in the American Folklife Center archive that were created by women, and that are too often overlooked.
