When Carlotta Bach and Desirey Sarpong Agyemang stepped on stage for their Battle performance of “Firework” on The Voice of Germany, it wasn’t just a duet — it was a meeting of two completely different musical worlds. Their performance caught attention not just for the quality of their voices, but for the stories behind them.

Both singers were coached by Giovanni Zarrella, and both brought something unique to the stage: Carlotta with her classical, angelic tone, and Desirey with her soulful, gospel-inspired voice. Instead of clashing, their styles complemented each other — and the coaches took notice.

Carlotta Bach was only 17 when she auditioned for The Voice. She comes from Dautphetal, a small town in Hessen, and is known locally for singing in church, school events, and weddings. With a background in classical music, she performed “Ave Maria” at her Blind Audition — a choice that set her apart from other contestants who leaned more toward pop and R&B.

Her performance earned her a four-chair turn from the coaches. She chose to join Team Giovanni, who appreciated her emotional precision and vocal purity. Later, in the Battle round, she was paired with Desirey for “Firework” — a pop song far outside her comfort zone. Despite that, she adapted to the challenge, and her classical tone added an unexpected layer to the duet.

Carlotta moved on to the Teamfights and performed “You Raise Me Up,” again showcasing her high range and emotional delivery. Although she didn’t make it past that round, her voice left a strong impression — particularly for its clarity and maturity at such a young age.

Desirey Sarpong Agyemang, originally from Duisburg, grew up with gospel music and church choirs. With Ghanaian roots and a childhood partly spent in Barcelona, her influences span cultures and styles. She’s not only a singer — she also studies business psychology and works part-time as a recruiter.

Her musical background comes mostly from practice and performance rather than formal training. She’s a member of the gospel choir Leslie B. Harmonies and had years of experience performing in church settings. That deep, soulful energy was clear in her performances throughout the show.

Desirey’s voice brought a rich contrast to Carlotta’s in the “Firework” Battle. Her powerful delivery helped her move forward into the semifinals and eventually the finale. In the final episode, she performed her original single “Break of Day.” While she didn’t win — finishing second behind Malou Lovis Kreyelkamp — she stood out as a consistent favorite throughout the season.

While their paths on The Voice diverged, Carlotta and Desirey each left a mark. Carlotta continues to pursue music alongside her studies, even playing piano at the German Television Awards. Desirey is balancing her academic and professional life with music, and her fans are watching to see what she does next.

Their shared performance of “Firework” wasn’t just a highlight of the season — it was a quiet reminder that powerful things can happen when different voices come together with mutual respect.

It was truly impressive how two such different voices, singing styles, and personalities could blend so harmoniously. Choosing to take both singers forward was a smart and well-deserved decision. Enjoy the performance below.
