East Oakland's Souls of Mischief are members of the loose underground hip-hop consortium known as Hieroglyphics. The group consists of four erudite but hardcore MCs -- A-Plus, Phesto, Opio, and Tajai -- whose mindset combines chaos, danger, and the avant-garde, all from an intellectual B-Boy perspective. Their 1993 debut album, 93 'Til Infinity, produced an early-'90s anthem of the same name and spawned a movement toward bohemian yet rugged hip-hop. The crew drew comparisons to De La Soul and A Tribe Called Quest for their abstract, whimsical style of storytelling.
