The crew known as K.M.D. first came to be known in 1989 as affiliates of Def Jam Recordings' highly talented trio Third Bass, an affiliation that would one day prove its irony. K.M.D. member Zevlove X contributed the concept and a compelling verse on the classic Third Bass jam, "The Gas Face." The crew composed primarily of Zevlove and DJ Sub-Roc kept close ties with emerging talents Third Bass for a couple of years, then went on to record their debut Mr. Hood on Elektra Records in 1991. On Mr. Hood, K.M.D combined lighthearted humor with divisive political rhetoric, but the overall sentiment was one of youthful positivity. The album featured production from the Stimulated Dummies and a guest spot from Brand Nubian. "Peach Fuzz," a tale of young romance, rippled momentarily, but the crew could not capitalize on their connections to 3rd Bass (even with a "Gas Face" reprise entitled "The Gasface Refill").
