Minneapolis rapper Slug (aka Sean Daley) has been at the forefront of underground rap so long it's hard for hip-hop heads to remember when Atmosphere wasn't a household name. Backed by DJ and producer Ant, Slug created a revolution of emotionally raw lyricism wherein his unbridled ego—and the defense mechanisms and underpinnings that created it—were ever-present. More than 20 years down the road, his discography is as much the soundtrack of a generation and subculture as it is a catalogue of desperate but defiant barstool poetry. In advance of a show at the Albuquerque Convention Center, Slug spoke with the Alibi.
