There was something overwhelmingly familiar about this singer when this song came up on my Discover Weekly recently so of course I had to research. Turns out she's the sister of Waxahatchee lead, Katie. Allison & Katie have done all sorts of work together and separate in the DIY/Indie scene, most notably the band P.S. Eliot. This song comes from Allison's debut solo album with Merge Records - came out one year ago (January '17). Happy to make your acquaintance, sis, and welcome to TMIS.
RIYL: Waxahatchee, Girlpool, Ratboys, Frankie Cosmos
