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), as well as likeminded locals such as MC Musab, Mr. Gene Poole, and the Abstract Pack, forming an underground hip-hop clique dedicated to freestyling, clever and complex lyrics, and anti-gangsta positivity. In 1998, Atmosphere released their debut album, Overcast!, which quickly became regarded as an underground hip-hop classic thanks to Slug's deeply personal, poetic musings, as well as Ant's bare-bones -- but inventive -- production. The group continued to put music out during the next couple of years, including the free download Strictly Leakage in late 2007, a near-party album that they followed up with When Life Gives You Lemons, You Paint That Shit Gold in April 2008, a record that featured plenty of live instrumentation and guest background vocal spots from Tom Waits and TV on the Radio's Tunde Adebimpe.
