Mtshali, also known as Mandla the DJ, was in partnership with Noxious Deejay, who was a solo music producer at the time, while Nyathi was a promoter who later became a DJ. The duo often spent time together before they eventually became friends and supported each other during their respective gigs.^[2]

They create house music containing elements of afro house and Deep house, combining live instruments such as bass, keyboards, percussions, flute, and vocals with samplers, effects and synths.^[1] Explaining their musical style:

Different songs give us different feelings and it's almost as if we can feel the energy or potential to get people on the dance floor, as well as visualise how people will move to the music. A lot of music moves us emotionally, whether it makes us sad, happy, hyper, energetic or relaxed. We find music to be extremely powerful.^[2]
