Atmosphere are a hip-hop group from Minneapolis centering around rapper Slug (aka Sean Daley). The son of a black father and a white mother who divorced when he was a teenager, Slug became entranced with hip-hop, graffiti, and breakdancing, and formed the Rhymesayers collective with two high-school friends — Siddiq Ali (Stress) and Derek Turner (Spawn). After some early gigs as Urban Atmosphere, where Slug DJed behind Spawn's rhyming, the pair hooked up with producer Ant (Anthony Davis).
