Dip an ear anywhere in Group Doueh's back catalog, and you'll find your head swarmed by intense Sahara Desert blues rock that makes American bands' version sound enfeebled and earthbound. Thanks to local label Sublime Frequencies, Group Doueh's mantric, soulful sonic mirages have spread from their African origins to open Western minds, and now, finally, to Nectar's stage. The new Zayna Jumma streamlines Doueh's sprawling jams into coiled songs that sting and uplift in equal measure. Expect transcendence. (Nectar, 412 N 36th St, 632-2020, 8 pm, $10, 21+)
