Most alt-R&B tracks are centred around more or less the same thing – love. Love in all its agony, love in all its euphoria. But Nin-ja wants to dig deeper than that. The singer-songwriter’s just released her new single Lockjaw where she sings candidly about her struggles with anxiety. Nin-ja’s been in the music game for about four years now, but after taking a brief hiatus, she’s back with a new single and more honest than ever.
