In 2018, Bridgers teamed up with fellow indie singer-songwriters Julien Baker and Lucy Dacus to form the supergroup Boygenius, signed to Matador Records. They released three songs in August 2018 and subsequently announced an eponymous EP, which was released on October 26, 2018, to widespread acclaim. Pitchfork called the collaboration "magic". The band toured the U.S. in November, appearing on Late Night with Seth Meyers and the NPR Tiny Desk. In January 2023, Boygenius reunited and announced their debut album The Record, which was released on March 31, and released singles "$20", "True Blue", and "Emily I'm Sorry". Bridgers has called the formation of the group "kind of an accident," wherein each of the members were simply fans of each other's work and then became friends. Both Dacus and Bridgers had opened for Baker on separate tours in 2016, and they all ran in similar circles as young up-and-coming performers navigating the indie scene.
