Where: London, U.K.
After cutting his teeth as an MC in East London youth centers, Tempa T (who also goes by the handle Tempz) truly burst out of the underground with the release of smash-and-grab anthem "Next Hype." Although his retro '80s hairdo makes Tempa T easy to spot—he's quick to point out that he has the most famous high top in grime—his fierce delivery and manic live energy are what have really vaulted him into the limelight. Also affiliated with the Slew Dem crew and the No Hats No Hoods label, he's currently finishing up his debut album.
