KCRW’s Private Playlist is a listening session with Southern California’s most notable musical figures in their private creative environments. Musicians Jay Som (Melina Duterte) and Palehound (Ellen Kempner) were individually well-established on the indie circuit (and mutual fans) when they met backstage on a double bill in Sacramento in 2017. Almost immediately, they bonded over a range of shared experiences, most pointedly as queer women of the same generational cohort in the music industry. Following an auspicious 2018 jam session, they formalized their musical partnership with the formation of Bachelor. The duo’s debut album, “Doomin’ Sun,” was recorded over two weeks in a rented Airbnb in Topanga Canyon in early 2020, replete with a piano and a hot tub. Treating the sessions as a kind of extended sleepaway camp, the result is a testament to the playful, free-associative nature of their collaboration.
