[1][2] He is best known for his work as the touring guitarist and music director for singer Solange Knowles, and his collaborations with musician Dev Hynes.
[3] In an Interview magazine article, Cook said that his family moved to Atlanta, Georgia during his "very formative years, when I was 9 to 13 or 14", and he taught himself guitar and playing by ear while watching VH1 Classic and listening to Prince's music.
[1][10][5] Cook worked on Knowles's 2016 album A Seat at the Table, co-producing and playing bass guitar on the track "Don't Touch My Hair",[11] which reached number 91 on the Billboard Hot 100.
[14] In 2021, he served as the music director and guitarist for cellist Kelsey Lu on the latter's operatic project This Is a Test at The Shed in New York City.
[15][16] While touring with Solange, Hynes, and Chairlift, Cook wrote songs and music for his own solo career, where he goes under the moniker Starchild & the New Romantic, which was inspired by the P-Funk collective as well as Prince.
The name was based on frequently used slang words "crucial" and "vicious" at the time and he likens the theme of the songs to diary entries from his teenage years.
