As the debut EP from Leith makes clear, when it comes to fertile songwriting territory, teen angst ain’t got nothing on quarter-life crises. Birthdays in July is the UK-based Canadian alt-pop singer’s document of being 25—and all the existential dread that goes with it. While the luminous “Love Vibes” opens the EP on a seemingly optimistic note, bottling up the nervous rush that accompanies a potential new romance, Leith probes deeper into the insecurities that spur those moments of doubt. “I’m just a kid, don’t have a clue,” she confesses on “Satellite”, a slow-building dance-pop anthem that fuses the internal monologues of Lorde with the strobe-lit drama of Robyn, while the urgent “What Does That Make Me” amplifies that self-loathing to an almost uncomfortable degree (her efforts to win the affections of a disinterested partner prompt her to proclaim, “I’m so pathetic lately”). But with the psychedelic acoustic sway of “Big Trees”, Leith eventually finds a moment of peace by getting out of her head and into nature.
