Jang Da-hye, better known by her stage name Heize, is a South Korean singer, rapper, songwriter, composer and producer currently signed to P Nation. The name Heize was inspired by the name of an American rapper Angel Haze, but instead of using the same English spelling, she decided to use Heize instead of Haze, because that was the spelling that came to mind. After making her debut in 2014 with the EP Heize, she gained attention after appearing on the second season of South Korean reality show Unpretty Rapstar. Shortly after, her breakout hit “Star” reached the top of the music charts.

Unpretty Rapstar is a South Korean rap competition TV show that airs on Mnet. It is known as the female counterpart of Show Me The Money. The contestants compete with each other to get a chance to participate in the new song that the producers made.
