The album title points to transformation and becoming something new. MuusikaPlaneet reports that the songs may initially sound like they centre on a painful breakup, but 17th wave describes a wider idea: passing through emotional difficulty, healing and finding the courage to continue.
That change is expressed through both the words and the music. The album’s instrumental work has a central role, while its lyrics are also an essential part of the whole. 17th wave said the two elements complement each other, and credited Lige with responding to and developing the ideas and messages brought into the collaboration.
Lige described the studio process as a natural exchange in which one idea could grow into something neither artist might have reached alone. He also said that shaping the album as a complete journey was an engaging part of his work as producer: the sound moves from darker territory towards a brighter and softer feel.
