Detroit’s own Elzhi (aka Jason Powers) accomplished something special in 2011: He remixed Nas’ Illmatic — one of the most revered hip-hop albums of all time — into Elmatic, a stunning re-imagining that combined his adoration for the original with fresh invention. Critics were love-struck. It didn’t hurt that he was already one of the most respected emcees around, serving on the front lines during Detroit rap battles in the ’90s, touring as a member of Slum Village in the ’00s, and releasing solo mixtapes that are now underground classics. He’s an intelligent word-twister, delivering complicated rhyme schemes with bold clarity. Elzhi is currently on a world tour in support of a new album set to release this fall. Doors at 8 p.m. at St. Andrews Hall, 431 E. Congress St., Detroit, 313-961-8961; $10.
