The rare youngish American rapper to get featured in highbrow British magazine the Wire, JPEGMAFIA (aka Jamaican American MC Barrington Hendricks) has used his experience of racism in Alabama and travels in the air force to shape his lyrical outlook and sonic approach—both of which are among the most galvanizing in modern hip-hop. Hendricks's military service has likely conferred a rugged discipline to his MCing and production skills—as well as a biting cynicism and darkness that are exhilarating. His latest album, 2018's Veteran, is a wild ride through rhythmic and verbal extremism. JPEGMAFIA's set is destined to be a Block Party highlight. by Dave Segal
