Quoting from the notes for this video on Tinariwen's YT channel:
“A thousand miles from their homeland in northern Mali, across a vast expanse of desert, the music of Tinariwen has found shelter in the hearts of six young musicians from M’hamid el Ghizlane (in southern Morocco). They were only boys when the desert rockers first visited their home, back in 2006, but they saw an immediate reflection of their own dreams and aspirations in the music they heard. In the years that followed they learned the Tinariwen songbook note for note, word for word, even though they couldn’t speak a word of Tamashek, the language of the Touareg.
When Tinariwen returned to M’hamid in 2016 to record a new album, those young disciples from M’hamid had achieved a remarkable mastery of the desert guitar repertoire. The torch had been passed from hand to hand and heart to heart across the great desert. The young musicians from M’hamid were invited to perform Abdallah’s ‘Sastaqanam’, standing in for their older brothers and playing with uncanny fidelity. But first the members of Tinariwen wrapped new turbans around the heads of their young acolytes, marking not only the passage from boyhood to manhood according to ancient desert custom, but also the transmission of their music across the generations, a transmission that is taking place in the hearts of youth from every corner of the great Sahara.”
