Not many young Australian engineers can boast the wide array of high-profile artists that Sydney’s Antonia Gauci has stacked up on her CV. Her work spans veteran rockers (Cold Chisel, Birds of Tokyo), bustling electronic projects (What So Not, Vallis Alps), and sing-along indie rock (DMA’S, Body Type). She has also helped to bring out the best in major pop artists like Troye Sivan and Kesha, and leads the dreamy alt-pop trio GAUCI alongside her brother David and collaborator Felix Lush. As she branches out from engineering and mixing to more cowriting and producing credits, Gauci has been shepherding artists’ idiosyncratic visions from any number of different angles. Whether it’s about getting the perfect amount of guitar in the mix or sending a dance track straight into the stratosphere, her trusted expertise is deepening all the time.
