Tinariwen (Tamasheq: , with vowels , pronounced tinariwen "deserts", plural of tenere "desert") is a Grammy Award-winning group of Tuareg musicians from the Sahara Desert region of northern Mali. The band was formed in 1979 in Tamanrasset, Algeria, but returned to Mali after a cease-fire in the 1990s. The group first started to gain a following outside the Sahara region in 2001 with the release of The Radio Tisdas Sessions, and with performances at Festival au Desert in Mali and the Roskilde Festival in Denmark. Their popularity rose internationally with the release of the critically acclaimed Aman Iman in 2007.

In 1998, Tinariwen came to the attention of the French world music ensemble Lo'Jo and their manager Philippe Brix. That group traveled to a music festival in Bamako and met two members of the Tinariwen collective. In 1999 some members of Tinariwen traveled to France and performed with Lo'Jo under the name Azawad. The two groups organized the January 2001 Festival au Desert in Essakane, Mali with Tinariwen as the headliners, and in close cooperation with the Belgian Sfinks Festival. The festival brought much outside attention to Tinariwen. By the end of 2001, Tinariwen had performed at WOMAD and Roskilde. Their debut CD, The Radio Tisdas Sessions, was recorded by Justin Adams and Jean-Paul Romann at the radio station of the same name (the only Tamashek-speaking station in Kidal, Mali) and released in 2001. It was Tinariwen's first recording to be released outside of northern Africa.  Since 2001 Tinariwen have toured regularly in Europe, North America, Japan, and Australia; often appearing at large world music/alternative festivals like Glastonbury, Coachella, Roskilde, Les Vieilles Charrues, WOMAD, FMM Sines, and Printemps de Bourges. Tinariwen gained more attention overseas in 2004, with their first UK performance at the largest free African music festival in the country, Africa Oye. Their 2004 album Amassakoul ("The Traveller" in Tamashek) and its 2007 follow-up Aman Iman ("Water Is Life" in Tamashek) were released worldwide and gained the notice of celebrity fans including Carlos Santana, Robert Plant, Bono and the Edge of U2, Thom Yorke of Radiohead, Chris Martin of Coldplay, Henry Rollins, Brian Eno, and TV On The Radio. In 2005 Tinariwen received a BBC Award for World Music, and in 2008 they received Germany's prestigious Praetorius Music Prize.  Also since 2001, the Tinariwen collective has added several younger Tuareg musicians who did not live through the military conflicts experienced by the older members but have contributed to the collective's multi-generational evolution. New members include bassist Eyadou Ag Leche, percussionist Said Ag Ayad, guitarist Elaga Ag Hamid, guitarist Abdallah Ag Lamida, and vocalists Wonou Walet Sidati and the Walet Oumar sisters. The band's 2009 album Imidiwan (Tamashek for "Companions") was recorded in a mobile studio by Jean-Paul Romann in the village of Tessalit, Mali.
