In 1984, Prince was on top of the world, with a No. 1 album and later a No. 1 movie, both named Purple Rain. Little did Prince know then how widely his projects' influence would spread, or the ways in which they might translate — literally. Three decades after the film first premiered, it got a remake filmed in Niger, featuring members of a nomadic group of people known as the Tuareg.

The Tuareg, known amongst themselves as the Kel Tamasheq, have long been recognised as warriors, traders and travellers of the Sahara Desert - known both for their grace and nobility as well as their fierce reputation. Tuareg communities in the Sahara, who have often felt overlooked and unrepresented by their governments, have been seeking self-determination for generations.

For the musicians performing on Wednesday in the Festival au Désert as part of the Lincoln Center Out of Doors series at the Damrosch Park Bandshell, the path from there to here has included an Islamist takeover of their Saharan homeland, followed by a religious war on music and then a French-led military intervention.
