On Hail The Sun's latest full-length, Mental Knife, Melero tackles that constant need for self improvement and his obsession with making up for lost time in a way that is both unabashedly honest and artistically innovative. The title of the record stems from the idea of cutting out those aspects of your life that don't contribute to a more fulfilling existence. The subject matter largely centers on trying to develop a genuine confidence that allows you to acknowledge your own imperfections and provides the strength necessary to work towards correcting them.
