Hieroglyphics, also known as the Hieroglyphics Crew and Hiero, is an American underground hip hop collective based in Oakland, California. The collective was founded in the early-1990s by rapper Del the Funky Homosapien. The collective is currently composed of rappers Del the Funky Homosapien, Casual, Pep Love, producer/manager Domino, DJ Toure, and the four individual members of the rap group Souls of Mischief: Phesto, A-Plus, Opio, and Tajai.
Since their inception, Hieroglyphics have found a following largely through their live concerts, podcasts ("Hierocasts"), and promotion through their website.
The collective uses a three-eyed, straight-lipped face logo that figures prominently on their albums, website, stickers, and clothing.
