Phoenix Heart is an ambitious metal project centered around the concept of the human soul rising like a phoenix's heart from the depths of darkness. The project emphasizes the notion that we become better versions of ourselves and develop into kinder, more experienced individuals through trials and personal growth.

The music primarily explores life experiences and our connections with others, whether through friendships or romantic relationships. The overarching theme of the music revolves around personal development through these connections and our ability to respond to challenges.
