In the spring of 2013, the self-professed Valley Girls released a four-song EP, Get Deap!, produced by Lars Stalfors (Matt and Kim, the Mars Volta, Cold War Kids). Their full-length debut, Sistrionix, arrived that same year and was also produced by Stalfors. Their sophomore effort Femejism was issued three years later. Produced by Nick Zinner (Yeah Yeah Yeahs), the album restrained some of the crunch assault of their debut, showcasing a side of Troy that reflected vocal influences like Karen O, Courtney Barnett, and Chrissie Hynde.
2020 saw them release a collaborative album with The Flaming Lips, to much critical acclaim. In 2021, they release their Digital Dream EP featuring jennylee, KT Tunstall, Peaches, Soko and Jamie Hince.
