Killah Priest made his first appearances on such Wu-Tang side and solo projects as Gravediggazâ 6 Feet Deep, Olâ Dirty Bastardâs Return to the 36 Chambers, and Genius/GZAâs seminal Liquid Swords. His contributions to those releases â especially Liquid Swordsâ âB.I.B.L.E. (Basic Instructions Before Leaving Earth),â essentially a Priest solo track â paved the way for the release of the MCâs acclaimed debut album, 1998âs Heavy Mental, and a lengthy and respected career in the hip-hop underground. In addition to his prolific solo work, he was an integral member of the groups Sunz of Man, the HRSMEN (aka the Four Horsemen), and Black Market Militia.
