Tilly Christiansson is a Swedish singer and songwriter from the island of Öland. Having written her first song at age 11, she later discovered a love for country music during her teenage years. Based on the UK country scene in London between 2012-2017, she performed both as a solo artist and as a member of duo Fifth Floor. She took the stage at legendary venues such as the original Hard Rock Café and The Troubadour, and performed outside the BBC headquarters for BBC Music Day.

Tilly's influences range from powerhouse country singers such as Carrie Underwood, and skilled songwriters like Cam & Miranda Lambert, to cheeky British guitar band McFly and the melodic pop culture of Sweden. In 2023, she released a Swedish and an English version of the same song, 'Här på ön' (or 'By the Sea'), which was frequently played on regional radio station P4 Kalmar.
