In 2017, she released her pop-ballad, "Polluted of the Loving Ones", debuting her solo project. The same year, Marie discovered her entrepreneurial spirit and co-founded the music collective Hummingbird Tapes, which brings together musicians to co-create works of music on retreats in an isolated space.
Her latest release ‘Dreaming’ in collaboration with Uk-based band Cherry Blossom Season was described as “a bubblegum pop head-bob”.
