The U.M.C.'s was an American hip-hop duo from the borough of Staten Island in New York City.
The group was comprised of Hass G and Kool Kim, who released the critically acclaimed, full-length album Fruits of Nature in 1991, which garnered chart success with the duo's #1 Billboard Hot Rap Single "Blue Cheese" and #2 Hot Rap Single "One To Grow On." In 1994, the duo released its sophomore album, Unleashed but split up soon after.
Since the group's break-up, Hass-G has focused on producing music, most notably garnering a #1 hit for Lil Kim featuring 50 Cent, with "The Magic Stick." Kool Kim reinvented himself as the controversial underground emcee NYOIL.
