Killah Priest made his first appearances on such Wu-Tang side and solo projects as Gravediggaz’ 6 Feet Deep, Ol’ Dirty Bastard’s Return to the 36 Chambers, and Genius/GZA’s seminal Liquid Swords. His contributions to those releases — especially Liquid Swords’ “B.I.B.L.E. (Basic Instructions Before Leaving Earth),” essentially a Priest solo track — paved the way for the release of the MC’s acclaimed debut album, 1998’s 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.
