A Tribe Called Quest were without question one of the most progressive and crucial rap groups of the 1990s. Along with their brothers and sisters in the Native Tongues -- a crew that also included the Jungle Brothers, Queen Latifah, De La Soul, Monie Love, and Black Sheep -- Tribe struck a natural balance between ruminative and carefree lyrical content, examining personal and deep societal issues without forgetting to have a good time.
