Rationale unveiled the first track from his new EP, 'Vessels', today. Prodigal Son was posted on New Music Friday lists across the globe, with Clash Music describing the song as "Powerful, stirring, and honest". Rationale explains: "'Prodigal Son' is an autobiographical song that came around accidentally. It explores my relationship with my biological father at first but if I'm really honest, it also explores the relationship that a lot of my friends have with their absent fathers." Take a listen HERE.
