Criolo built his reputation in the São Paulo hip-hop underground. Alongside DJ DanDan, he’s been financing and hosting the Rinha dos MC’s, an infamous local freestyle battle. His first record was released in 2006, quickly becoming a favorite for local hip-hop heads. The songs focus less on favela culture and more on daily life in less crime-ridden streets. His career has taken a turn lately, as he attempts to incorporate singing into the potted style of Brazilian rap.
