Finn O'Sullivan is an indie folk/pop singer-songwriter based in Longmont, CO. She explores love and heartbreak, patriarchal privilege, the worlds of her favorite fictional characters, and the endless what if's that keep her up at night. 

Former Rolling Stone managing editor calls O’Sullivan “the lovechild of Taylor Swift and Phoebe Bridgers,” and that marriage of songstress genius comes out in her lyricism and in her fearlessness in exploring not only the depths of feeling, but also some serious badassery. Lyrics are often where a song begins for O’Sullivan. “When I write a song,” she says, “it’s not based on a melodic idea or a chord progression, but on a concept, a lyrical idea.” Her lyrics range from old soul to fresh and bold, and her clever, catchy, and sometimes melancholy tunes simply get stuck in your head. 

O’Sullivan has shared the stage with Langhorne Slim, Carsie Blanton, Rainbow Girls, Olivia Barton, and a host of local Colorado talent. The title song of her first LP, When the Power Comes Back On (2020), won the Song of the Year award in the prestigious John Lennon Songwriting Contest.
