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.
