The Cameroonian musician and singer Laetitia Tamko, who performs as Vagabon, makes lo-fi indie rock songs that swing from sweetness to smashing with aplomb. Nigerian composer/performer Nnamdi Ogbonnaya’s satiric/schitzoid blend of hip hop, math rock and jazz is also on the bill, as is Portland psych-folkie Lisa/Liza, at SPACE Gallery (538 Congress St., Portland) at 8 p.m. Tix: $8-$10 (all ages). 828-5600. space538.org.
