The members of Malian Tuareg desert blues band Tinariwen came together while living in Libya's military refugee camps in the early 1980s. Recorded in a remote section of the South Eastern Algerian desert, Tassili, the group's fifth studio release, sets a different course than previous efforts. On the long player, the group strips down their sound—trading Stratocasters for acoustics, employing the use of un-amplified percussion — and, for the first time, invites a few notable outsiders to appear. Guests include Tunde Adebimpe and Kyp Malone of TV on the Radio, who ventured to the desert to record with the band, in addition to Wilco guitarist Nels Cline and members of the Dirty Dozen Brass Band. Returning to the their beginnings, Tassili recreates the origins of Tinariwen's music—acoustic songs performed by an open fire, much like the refugee camps where they originated.
