TINARIWEN

Rebel Touaregs (nomads from a North African region extending from Algeria to Nigeria and from Mali to Libya) play traditionally influenced music with electric instruments and sing songs in independence for their politically troubled people.  Sort of a Rage Against the Machine with a desert, blues fells.  (10/29, 8 p.m., $28-$22.  Somerville Theatre, 55 Davis Sq., Somerville, 617-876-4275, www.worldmusic.org.)
