Madd Joker (aka Poppa Jam and Joker Ranking) first earned local notice with reggae groups like Revelation Hi-Fi and Revelation International.
He began rapping in the 1990s, co-founding Kulcha Records with King Jahzzy, though he is still known to mix reggae in with his beats. His full-length Collabs of Napalm Vol. 1 was released in 2012.
