Mitski’s sound and writing style have evolved on almost every album she’s released. Her early album “Retired from Sad, New Career in Business,” from 2013, relied on big orchestral swells alongside electronics. Her breakout, “Bury Me at Makeout Creek,” released the following year, felt at times like a punk-rock sprint of guitar and drumbeats. On “Be the Cowboy,” her 2018 album, her production was more lush and full without wholly abandoning her flair for fuzzy and distorted guitar work. “Nothing’s About to Happen to Me” is a bit of a mashup of many of Mitski’s past endeavors, featuring big orchestral swings and moments of loud, frantic guitar, but its formal ambitions feel secondary to its expansive lyrical themes. On a line level, the songwriting comes alive with imagery and ache, such as on the album-closing song, “Lightning”—“When I die / Could I come back as the rain?” But the most fascinating quality of “Nothing’s About to Happen to Me” is how Mitski manages to embody an “I” with the full sense and spirit of a wonderfully complicated central character who is orbiting heartbreak and loss. In the song “Cats,” the narrator anticipates the absence of someone she still loves, a void being filled by two cats who sleep in bed with her at night. “Instead of Here” opens with a knock on the door and the woman depressed and lying on the floor instead of answering, with “death crouchin’ ” beside her. On “I’ll Change for You,” a listener overhears the woman on a drunken phone call, insisting that she’d do anything to be loved again—that she’s willing to change, to become whoever is needed to make the person return.
