Heize will be releasing her new EP titled '///' on June 26, marking 6 months since the release of her digital single "Star."  Each '/' in her new EP '///' has a symbolic meaning. The symbolic terms are 'you', 'dark clouds' and 'rain.'  Furthermore, a new hidden track called "Since It's Raining" (working title) is set to be unveiled on a rainy day, going for an interesting approach.

Stay tuned for more info on the release.
