Mag-2 was essentially filled with the best elements of "The Parrots," a highlife band in which Amponsah was the lead guitarist. Their primary task was to entertain soldiers and with the army tour bus, perform from town to town as well as in reputable venues in the captial. Enticed by the style of music Rob had proposed, Mag-2 backed the Ghanaian sensation on two of his most astonishing records - his first and second albums -"Funky Rob Way" and "Make it Fast, Make it Slow," both of which were recorded at Essiebons studios in Accra. Despite Rob's training and musical education, Amponsah was responsible for the vast majority of the compositions, such as building the chord progression and arranging the horns that Rob craved. Rob would even wait for the Mag-2 maestro's cue to begin singing.
Despite early successes, a once-unflinching interest in Afrobeat began to wane by the early 1980s and Disco Boogie rapidly became the vogue style around which label owners and
music producers sought to capitalize upon. The style Rob had shaped his career around was in decline and an adequate income consequently became a major concern, forcing him to travel to Hamburg, Germany in search of a financial backer.
