Routine is Chastity Belt’s Annie Truscott and Jay Som’s Melina Duterte. Their collaborative project’s debut EP, “And Other Things,” emerged out of time the partners spent in Joshua Tree. For Routine, Truscott wrote a lot of the material and sings lead, while Duterte accompanies her (she also wrote arrangements and did the recording and mixing). There’s a lot of the Jay Som sound on this record, and it has a similar vibe to the music on last year’s gorgeous “Anak Ko,” bright and kind of airy, full of bold sounds and hooks. But the sound of Routine is just as much about Truscott’s songwriting and singing, which has the breathy weight of Kristin Gundred from Dum Dum Girls or Hope Sandoval. Her voice is beautiful, and she uses it to great and varying effect across the five songs on the EP—from contemplative on “Cady Road” to disappointed on “Numb Enough” to passionate on “And Other Things”—Truscott sings really expressively. Like Duterte, Truscott has a gift for writing great melodies, and all the songs on the EP make an immediate impression, every song is packed with hooks and fascinating little sonic touches. All these songs also feel really personal, like letters sent off to a friend, and Truscott has mentioned that the EP is intended as a series of vignettes. It’s a tidy package of beautiful and compelling songs.
