Terakaft are a Tuareg family band that play their trance-like desert blues both around campfires in the Sahara and at clubs around the world. The group, whose name means “caravan” in Tamasheq, was founded in northern Mali by guitarist Sanou Ag Ahmed in 2001. He was joined in 2006 by his guitar-playing uncle Diara, who had been an original member of pioneering desert band Tinariwen, and in 2008 by Abdallah Ag Ahmed, Sanou’s younger brother. Terakaft’s new album, Alone, lyrically reflects the troubling political situation of the Tuareg, blamed by some for the terrorists who infiltrated northern Mali (many Tuareg now live in exile). While many songs feature chanted vocals that reflect their despair, a few express hope that things will improve. One doesn’t need to understand the words to grasp the music, as the stringwork has a mesmerizing feel. Drawing inspiration from Tuareg traditions, John Lee Hooker, and Dire Straits, their picked and strummed rhythmic style feels sui generis. Terakaft performs with Cheick Hamala Diabate’s Griot Street at 8 p.m. at Bossa Bistro, 2463 18th St. NW. $10. (202) 667-0088. bossadc.com.
