Disco 4 was among the perfect party-jam manufacturers in rap’s aged school, saving classics like “Move Using the Groove” and “GET IT DONE, GET IT DONE” for Enjoy through the early ’80s. Located in Harlem, the group shaped around Ronnie D, DJ Al Bee, Greg G, Mr. Troy, Nation, Kool Gee, and DJ Al Bee. A fraternal reference to Bobby Robinson — among the people was his boy — got them registered towards the Enjoy label (then your most popular place for hip-hop), but nepotism got nothing in connection with their traditional debut, 1980’s “Move Using the Groove.” A soft, quick-paced party monitor, it was accompanied by “GET IT DONE, GET IT DONE” in 1981 and “Nation Rock and roll and Rap” in 1982. That same season, they also made an appearance on Profile (after that in its infancy) with another membership track, “We’re on the Party.” Disco Four didn’t perform much more in the form of recording, aside from a 1986 one on Danya (“Obtain Busy”) along with a Profile Xmas record twelve months later.
