Endless energy courses through Agadez, the second album by Nigerian combo Etran de L’Air. It’s named for the city the band calls home, long an important center for the Tuareg people, a traditionally nomadic group that has produced some transcendent guitarists, including Tinariwen, Abdallah Oumbadougou, Mdou Moctar, and Les Filles de Illighadad. All electrify Tuareg stylings, fusing folk tradition with rock & roll sensibility.
