As we approached the stage, the Tuareg band Les Filles de Illighadad (Amaria Mamadalher, Fatou Seidi Ghali, Alamnou Akrouni, with Abdoulaye Madassane) transported us to a near trance. The long and looping, dry and distorted electric guitar grooves swirled around us, accompanying prodding percussion. The two intertwining guitars looped with repetition, creating a droning effect, while percussion provided a steady metronome, slow and pounding. On closer examination, the thumping sound came from a calabash gourd, half buried in water, inside a plastic washtub - an unique and unwavering rhythm. On top of this, we were drawn in further by alternating high pitched vocals, first from stage right, then from stage left, and back again. The vocal call and response swirled with stereo imagery. The music is played is called Tende, traditional music of the Toureg people of the Sahel region of North Africa. The spare instrumentation hints at the nomadic lifestyle. The tende is made from goat skin stretched over over a mortar, the water drum used is an overturned calabach in a washtub of water. The guitar is a recent innovation incorporated into the music.
