Sublime Frequencies co-founder Hisham Mayet travels like a tramp, carrying his bag of recording equipment on hitched rides and charter buses across Africa, Asia, and the Middle East. Out of the Saharan Desert, he‘s brought back Guitars From Agadez, 10 tracks of mind-bending guitar rock by Group Inerane. Bibi Ahmed‘s cyclical, psychedelic riffs are mesmerizing enough, but the group female vocals work like a prism refocusing a spectrum of sonic colors. These shrill howls and modulated chants float around the steady rhythms of surf rock and psych-blues. Above all, though, this record begs the question–when and how do we get to hear Group Inerane again?
