In the live recording of "Mildenhall," James Mercer performs at the Phaser Control Recording Studio in San Diego, showcasing his distinct lyrical style and melodic sensibilities. This performance occurred shortly after the release of the album "Heartworms" in March 2017. "Heartworms" marked a significant moment in The Shins' career, as it was their first album in five years, following "Port of Morrow" released in 2012. Mercer embraced a more personal and introspective songwriting approach on "Heartworms," likely reflected in the emotionally resonant "Mildenhall." The song itself draws inspiration from Mercer's experiences while living in England, highlighting his thoughtful narrative style. This intimate live session at 91X's X-Session also demonstrates The Shins’ commitment to engaging with fans and promoting new material in a relatable setting.
