Hayden Frances Dunham (born June 16, 1988) is a performance artist, designer, singer, songwriter and DJ.

[3][4] QT is a pop singer, portrayed by Dunham and sung by Harriet Pittard,[5] who promotes and is the living embodiment of the semi-fictitious DrinkQT energy drink.

Dunham originally wanted to do a song as a way to market a QT energy drink, and asked the producers to repeat the name regularly.

The concept drew comparisons to the 2002 science fiction film S1M0NE and the virtual Japanese pop star Hatsune Miku.

Dunham took a musical hiatus and worked on multiple art exhibitions and projects in this time,[22][23] notably a performance piece at MoMa titled 7 Sisters in early 2019.

[28] Hyd released a cover of Nick Cave and the Bad Seeds' "Into My Arms" in January 2022, produced by Easyfun.
