A rapper who keeps company with the indie rock crowd (she's signed to Philly label Don Giovanni), Sammus writes hip-hop paeans to geek culture—gamers, comics fans and so forth. She plays with a rotating cast of openers for this Mercury Lounge residency. Most notably, you'll find multi-instrumentalist Mal Devisa performing Sept 11, who works surprisingly textured tunes from a pared down framework: soulful vocals soaring over loops of understated bass guitar. Her strikingly direct tunes have garnered her quite a word-of-mouth reputation in the local indie scene, exploring resilence, displacement and isolation with a revelatory spirit. Also look out for hectic noise-duo Machinegirl (Sept 18) and self-described "future-soul" quintet Jelani Sei (Sept 25).
