HiDoraah, previously known as simply Dora, is the primary alias of the Atlanta-based Dora Williams, a nonchalant rapper who has recorded with brother Young Thug and sister Dolly White in addition to having released minimal solo material. HiDoraah and Dolly White released the collaborative Slimestas (2018) after contributing to Young Thug's I'm Up mixtape.

Dora Williams grew up in Atlanta, Georgia with ten siblings, including brother Jeffery, aka Young Thug. Amid regular appearances in Young Thug's videos, Dora and sister Dolly made their recorded debut on "Family," the finale of their brother's 2016 mixtape I'm Up. This unintentional contribution, a result of playful freestyling the sisters didn't realize was being recorded, led later that year to Dora Dolly's Family Ties mixtape. Dora shortly thereafter changed her performing name to HiDoraah. In 2018, she released a solo single, "Como Te Llama," and made multiple appearances on Young Thug's Slime Language, including the Dolly collaboration "Expensive." HiDoraah and Dolly, alternately known by then as Dolly White -- resumed work as a duo, and in 2019 released six assured and leisurely tracks bundled as Slimestas. ~ Andy Kellman, Rovi
