Without question the most intelligent, artistic rap group during the 1990s, A Tribe Called Quest jump-started and perfected the hip-hop alternative to hardcore and gangsta rap. In essence, they abandoned the macho posturing rap music had been constructed upon, and focused instead on abstract philosophy and message tracks. The "sucka MC" theme had never been completely ignored in hip-hop, but Tribe confronted numerous black issues -- date rape, use of the word nigger, the trials and tribulations of the rap industry -- all of which overpowered the occasional game of the dozens. Just as powerful musically, Quest built upon De La Soul's jazz-rap revolution, basing tracks around laid-back samples instead of the played-out James Brown-fests which many rappers had made a cottage industry by the late '80s. Comprised of Q-Tip, Ali Shaheed Muhammad, and Phife, A Tribe Called Quest debuted in 1989 and released their debut album one year later. Second album The Low End Theory was, quite simply, the most consistent and flowing hip-hop album ever recorded, though the trio moved closer to their harder contemporaries on 1993's Midnight Marauders. A spot on the 1994 Lollapalooza Tour showed their influence with the alternative crowd -- always a bedrock of A Tribe Called Quest's support -- but the group kept it real on 1996's Beats, Rhymes and Life, a dedication to the streets and the hip-hop underground.
