Morton (Jo Casters), Sherman (Herman Gillis) and Belluci (Roland Beelen) were the founders and most productive artists in the New Beat movement of 1987, releasing around an estimated 100 recordings in one single full year under a plethora of names when the sound peaked in popularity in the late 1980's.
The nickname "Morton-Sherman-Belucci" is allegedly a parody on the prolific 1980s Hi-NRG producer team of Stock, Aitken & Waterman.
