Lydia Kim, known professionally as KISAKI, is a Korean-Canadian singer-songwriter, producer, and musician based in Toronto. 

An alumni of Etobicoke School of the Arts' musical theatre program, Lydia competed in collegiate a cappella while receiving classic voice training. Known for dynamic and powerful performances (i.e. "tenderstrong"), she now collaborates with other international producers as a vocalist and lyricist in different genres including rock, pop, R&B, and jazz. Her EDM repertoire also include melodic dubstep, future bass, future house, psy trance, synthwave, and eurobeat.

She has released multiple tracks with high-profile underground music groups in doujin culture including EastNewSound, Nuzix, and Galaxian Recordings. Upon graduating from the University of Toronto's Masters of Music Technology and Digital Media program, she began to experiment with East Asian traditional sounds into her music.



Lydia lists MIYAVI, Lights, BoA, Lindsey Stirling, Lady Gaga, GRANRODEO, Sawano Hiroyuki, and Imagine Dragons as among her musical influences, as well as various productions with dystopian futuristic themes such as Akira, Ghost in the Shell, Attack on Titan, Final Fantasy, and Blade Runner. On July 16, 2021, she self-released her first EP, titled Heart Battery, where she wrote, produced, engineered, and recorded the majority of the EP by herself. In the following year, she released the companion remix EP, Battery (The Remixes), featuring Tephra, Sixtroke, KYN, and Riots Revenge.
