Hailing from the town of Portadown in the County Armagh in Northern Ireland, Hamilton made her appearance on the local scene alongside fellow alternative indie rock and folk artists such as No Oil Paintings and Ciaran Lavery. It wasn't long before her sound and style began to resonate with gig-goers and alternative music fans in the area. Her lo-fi, lush, and atmospheric sound began to attract attention after she put out her debut EP, Capricorn, in March 2015. The release received widespread critical acclaim, and Hamilton eventually found herself performing on BBC Radio Ulster's Across the Line show, with BBC Radio One's Huw Stephens also praising her skill and airing some of her material. The EP alone earned Hamilton a burgeoning fan base, with many critics and fans comparing her to the likes of Girlpool, the Moldy Peaches, and Karen Dalton. She then went on to write and record her debut full-length. The album, Parma Violets, saw release in May 2016 via Big Space Records. The record incorporated a wider and broader sound palette which had evolved since Capricorn; many of the songs had evolved from stripped-down, minimal, and bare acoustic numbers to more layered and lavish indie rock anthems. In order to promote the effort, Hamilton assembled a live band to tour the record as well as her previous material and also broke stateside with shows at SXSW in Austin, Texas and numerous appearances along the West Coast. All of that exposure eventually caught the attention of Canvasback Music/Atlantic Records, which signed Hamilton in early 2017. Her first release for the label, The Moths of What I Want Will Eat Me in My Sleep EP, arrived in July 2018 followed by a second EP, Wisdom Teeth, in early 2019.
