MUNSTER/ÖRTZE, GERMANY — Bringing together songwriter Claudia Heinrich-Witzenthaler and her 21-year-old son Felix Karl Josef, the German mother-and-son musical collaboration QUINTESSE feat. KARL JOSEF has launched their emotionally direct pop-rock single, “On My Way”. Rooted in authenticity, family connection, and unhurried artistic exploration, the track showcases Felix’s natural baritone voice in his debut professional studio recording.
Originally written as a deeply personal message to Felix’s sister Victoria as she persevered through years of setbacks to reach a major life milestone, the song’s core message has blossomed into a universal anthem. It speaks to anyone who has been doubted, held back, or made to feel that their dreams were unrealistic, capturing the courage it takes to keep moving forward despite uncertainty.

Drawing sonic and emotional inspiration from powerhouse singer-songwriters such as James Arthur, Lewis Capaldi, Tom Walker, and Passenger, “On My Way” follows a striking dynamic arc. Starting with restrained, vulnerable verses, the arrangement gradually builds in intensity and emotional strength, mirroring the psychological shift from doubt to confidence.
The production emphasizes authentic human performance over polished perfection, anchored by recurring guitar and saxophone motifs that reflect the personal instrumental backgrounds of mother and son.

The resulting collaboration highlights a rare organic synergy, blending a profound family story with a rich, growing pop-rock soundscape.
