Wedged on the Atlantic between Morocco and Mauritania, the occupied territory of Western Sahara has been in dispute since Spanish colonizers left over forty years ago. The people who live there are called the Saharawi, and one of their most popular (only?) musical exports is Group Doueh. An electric guitar master whose compositions are heavily influenced by western classic rock, leader Doueh (“doo-way”) formed his band in the early eighties. The songs are sung in Hassaniya Arabic and put out by globetrotting Seattle label Sublime Frequencies. (For an easy entry point, check out Dakhla Sahara Session, the rock album they released with French band Cheveu.) The performance also includes a screening of a new hour-long documentary about the band.
