With Claudinho & Buchecha and MC Marcinho as his influences, Isaac Daniel Júnior started his music career in the duo Zaac & Jerry with Rodrigo Silva dos Santos, aka Jerry Smith, giving himself the moniker MC Zaac. Their debut single, 'Nos Fluxos', was released in 2015 but it was their second single, 'Bumbum Granada', a year later which landed them in the charts. Shortly after however, Zaac & Jerry parted ways and MC Zaac set out on his own.
He released two singles - 'Te Jurupinga' and 'Vai Embrazando' - launching his solo career in his native Brazil, also reaching the charts in Portugal and Paraguay. Approached by Brazilian singer Anitta to collaborate, she and MC Zaac recorded 'Vai Malandra' along with rapper Maejor in 2017. In 2020, 'Bumbum Granada' reached 500 million views online.
