Producer, engineer, and composer Alex Epton has worked with a wide variety of hip-hop, indie, and dance artists, in addition to making experimental electronic music on his own. Once known as XXXChange, he rose to prominence as a member of the party rap group Spank Rock, producing their 2006 debut YoYoYoYoYo. He soon departed and became a prolific, sought-after producer and remixer, working with the Kills, Kele, Kylie Minogue, Thom Yorke, and others. He formed the group Win Win, who released three albums of trippy electronic psych-pop. Active as the in-house producer and engineer for XL Recordings' New York studios since 2014, Epton has worked with artists like Kali Uchis, David Byrne, and FKA twigs, in addition to writing music for films and commercials. He composed the soundtrack to the 2019 film 3OHA along with Lucinda Chua, and he released the abstract techno EP Episodic Buffer Vol. 2 in 2021.
