Based in Norfolk, Virginia, the ten-piece soul and disco group Mass Production had a series of super funky R&B hits in the late 70s and early 80s. Mass Production consisted of LeCoy Bryant, Kevin Douglas, James Drumgole, Agnes "Tiny" Kelly, Larry Marshall, Gregory McCoy, Rodney Phelps, Ricardo Williams, Samuel Williams, and Tyrone Williams. Their best-known song, "Firecracker", hit number four on the R&B charts in the late summer of 1979 and continues to be loved across dance clubs.
