She started off as a protégé of DJ Whiz Kid before deejaying for artists such as the Bad Girls and Shelly Thunder.^[2] She began deejaying for the group Digable Planets in 1994^[2] and was featured on "9th Wonder (Blakitolism)", the first single from "Blowout Comb", the second album from Grammy winning rap group Digable Planets.
