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.
