 Early on, Jolicoeur sported a unique style of African medallions, peace signs and uneven dreadlocks (known as the "De La Do").Paired with the positive messages of the group's debut effort, "3 Feet High and Rising", the image led to critics and journalists labelling the members as "the hippies of hip hop" (a title that the group was quick to refute with the release of the second album "De La Soul Is Dead" in 1991).David also vocalised the second and third chorus of Feel Good Inc by Gorillaz

Jolicoeur is also a member of the Spitkicker collective.
