Billie Marten Live in Concert

Originally from North Yorkshire, Isabella Sophie Tweddle began playing guitar at age seven. At nine, she began releasing music on YouTube in the form of pop song covers made mostly for the benefit of her grandparents living in France. After confirming her interest in music to her mother by age 12, in 2012 she went on the YouTube live music session channel, Ont' Sofa, to perform a cover of Lucy Rose's "Middle of the Bed.'' She was then invited by Rose to join her UK tour in October of that same year. In 2014, Marten released her EP Ribbon, setting herself up for a long and successful career. When asked about the origin of her stage name in a 2021 interview with Buzz Magazine, Marten said, "My name was difficult to say and spell. Firstly, it was after John Martyn, a need for simplicity. When I started doing gigs, I found that there would be misspellings, abbreviations and no one could find me on the internet -- I wanted something simple and something important and that was Marten."

In a 2014 interview with Teen Vogue, Marten was asked about what makes her worth listening to. She responded by describing her sound as, "[A] mix between acoustic and quite folky and a little indie." Marten's simplistic and stripped-down sound earned her a spot on The BBC's "The Sound of 2016" list, where she was described as an "adolescent prodigy."
