The basic recording features nothing but her voice, guitar, some effects, tape hiss, room noise, and the sound of fingers squeaking on the fretboard. This is a smart move, and it elevates the carefully understated songwriting to heights that studio production wouldn't approach.
Also of note here are two excellent covers. "Girls Just Wanna Have Fun" comes across as everywoman Cat Power, stripping down the song to turn the celebration into a plaintive lament. And the lesser-known "If I Give My Soul", by Texas country legend Billy Joe Shaver, makes the most of every ringing note, turning the song into a harrowing, field recording spiritual.
In short, fans of smart, appealingly honest, and lo-fi should make a point to pick this up; it's a grower.
