El Wali has been played on NTS shows including Posh Isolation's Copenhagen Report, with Long Live The Sahrawi Army first played on 21 November 2019.

El Wali was a Western Saharan folk music group who recorded an album, Tiris, in 1994. Their lyrics are "politically charged" and call for independence for the Sahrawi people; the album was described as "a call to arms—with national anthems, celebrations of political anniversaries, and religious pleas for peace". According to Sahel Sounds, the American label that reissued the album, it was recorded in Belgium and released in a limited run for the Belgian OXFAM. The band's music first appeared anonymously as "Polisario" on a 2012 compilation from the Sahel Sounds label, Music from Saharan Cellphones, before Tiris was released in 2019.
