The Train Song Vashti Bunyan

Bunyan released her debut album, Just Another Diamond Day, in 1970. The album sold very few copies and Bunyan, discouraged, abandoned her musical career. By 2000, her album had acquired a cult following; it was re-released and Bunyan recorded more songs, initiating the second phase of her musical career after a gap of thirty years. She subsequently released two albums: Lookaftering in 2005, and Heartleap in 2014. Source
