Juma Nature a.k.a. Sir Nature (born Juma Kassim Ally, in 1980) is a Tanzanian hip hop artist and a singer. He is the founder and member of a Temeke group called Wanaume, an informal group of rappers from the poor side of Dar es Salaam. In his last album, "Bongo Flava: Swahili Rap from Tanzania", many of the lyrics which are in his tracks include current problems within his country. Some problems he raps about include, "HIV/AIDS, the difficulty of meeting basic needs, class and wealth barriers, and holding your head high despite everything". One of Nature's well renowned songs is "Umoja wa Tanzania" which talks about a celebration within Tanzania and the sense of unity that it has exemplified. “Utajiju” (“You'll know for yourself") from Juma Nature's brand new album Ubin-Adam Kazi, is a song about people who like to poke their noses into others’ business.
