Having known the Clan since the mid-80s and produced for them since 1996, Mathematics is no stranger to the group. Starting off as GZA's DJ during the emcee's Cold Chillin' days, the producer has since gone on to create a diverse and memorable production catalog with the group, contributing tracks to The W and 8 Diagrams, as well as Ghostface Killah's Supreme Clientele, GZA's Beneath The Surface, Method Man's Tical 2000: Judgement Day and Method Man & Redman's Blackout!.
