Electronic group Mash'Allah, whose sample-heavy, collage-like tracks recall hip-hop, IDM, world beat, and EDM all at once, introduce another 'Scape to the city with Minorityscape, a fundraiser for Musicians Without Borders featuring, among others, two of the most versatile rappers in the city, Eze Jackson (pictured) and JuegoTheNinety. Jackson, who is headlining, is somebody you should already know from his solo stuff and from his work with Soul Cannon, while JuegoTheNinety, a buggy, Eminem-like MC, is one of the most exciting up-and-comers in the city. His "Sonny September" mixtape from last year was named number one on Al Shipley's top 10 list in City Paper's Top Ten issue. Also performing are Deva, Urban Shaman, and Flash Giordani, and there will be art from Arooj Qamar, WuQing Hipsh, and Justin McCraw. 8 p.m., Reverb, 2112 N. Charles St., (443) 447-4325, reverbcollective.com, $5.
