Killah Priest first made himself known to the hip hop world rapping on two songs on the Gravediggaz album 6 Feet Deep (which are "Diary of a Madman" and "Graveyard Chamber") in 1994, and followed this with two appearances on each of two Wu-Tang Clan solo albums, Ol' Dirty Bastard's Return to the 36 Chambers: The Dirty Version and GZA's Liquid Swords, both from 1995 (see 1995 in music). Liquid Swords in fact included a Killah Priest solo track titled "B.I.B.L.E. (Basic Instructions Before Leaving Earth)". Also in 1995, Priest's group Sunz Of Man with rappers Hell Razah, 60 Second Assassin, Prodigal Sunn, Shabazz the Disciple were signed to Wu-Tang Records and released three 12" singles through the label. Initially Sunz Of Man included Shabazz the Disciple, who had previously been in a duo with Priest called The Disciples Of Armageddon, .
Killah Priest's first solo album was Heavy Mental, released on Geffen Records on February 24, 1998. It mostly expanded on the themes of "B.I.B.L.E.", featuring religious references and allegory woven into commentary on African American society and history. The album was mostly produced by the Wu-Elements producers, a group of in-house Wu-Tang producers mentored by Wu leader RZA.
