Alexander Guy Cook is an English record producer. He first became known as founder of the influential record label PC Music in 2013; its signees included Hannah Diamond, GFOTY, Danny L Harle and Felicita. The label's style of exaggerated pop tropes grew to serve as the foundation of the hyperpop genre, which Cook is credited for developing and popularising. He later became more widely known as executive producer for Charli XCX. He has released solo music under both his name and aliases like Life Sim and DJ Warlord.
Cook formed the one-off project QT with musician Sophie and performance artist Hayden Dunham, producing the 2014 single "Hey QT". He released his first solo singles in that same year, and was named number 12 in the Dazed 100 for "redefining style and youth culture in 2015 and beyond". He served as executive producer on Charli XCX's mixtapes Number 1 Angel and Pop 2 (both 2017), and albums Charli (2019) and how i'm feeling now (2020).
Cook's first two albums, 7G and Apple (both 2020), both explored hyperpop and were met with critical praise. That same year, he won the Variety Hitmakers Innovator of The Year Award in 2020. In 2022, he co-produced the song "All Up in Your Mind" from Beyoncé's album Renaissance, which earned him a Grammy nomination for the Album of the Year, and he released his third album, Britpop, in 2024. He continued to produce for XCX with Brat (2024) and its remix album, earning him a nomination for the Grammy Award for Best Remixed Recording for his "Von Dutch" remix.
