„Fierce“ is an artistic alliance of four outstanding voices, united in a powerful manifesto of female strength. At the center is Debora Lavagnolo, the charismatic lead singer of Deep Sun. The classically trained soprano shapes the song with her clear, energetic voice and brings both her impressive stage presence and her many years of experience as a front woman to the table.
Laura Guldemond, singer and vocal coach, reinforces the formation with her irrepressible energy. Since 2019, she has been the voice of the Swiss power metal band Burning Witches, which was founded in Brugg, Aargau. With her wild performance and passion for old-school metal, Laura transports the untamed spirit of the 80s into the here and now. This collaboration also marks a special chapter: the first official cooperation between these two heavy metal bands from the small town of Brugg.
Ambre Vourvahis, the voice of the German symphonic metal band Xandria since 2022, brings another facet to this ensemble. With a Greek-French background and experience in choir and musical singing, she lends the song a clear, luminous tone and represents the modern symphonic metal aesthetic.
The alliance is completed by Dani Nell, the singer of the Swiss modern metal band DevilsBridge. With her distinctive voice and powerful stage presence, she adds extra depth and emotional dynamism to „Fierce.“
Together, Debora, Laura, Ambre, and Dani create a musical unity with „Fierce“—classical, epic, wild, and unshakeable. This collaboration is much more than a feature: it is a statement of solidarity, diversity, and empowerment in metal. „Fierce“ stands for the strength of women in all their facets – courageous, passionate, unstoppable.
On September 26, 2025, this anthem – carried by four extraordinary voices – will be released on all streaming platforms. A musical call that celebrates the inner strength that resides in each of us.
The song „Fierce“ was released in 2025 on the Deep Sun album Storyteller – at that time sung exclusively by Debora Lavagnolo. But from the very beginning, the singer knew that this song was meant for something bigger. „Even as I was writing it, I felt that Fierce was more than just a song – it was a manifesto. It was clear to me that this message of strength and unity should be carried by several women,“ says Debora.
So collaborating with Laura Guldemond from Burning Witches was an obvious choice for her. „Laura’s voice is so uniquely powerful that no one else would be better suited to embody the raw power of Fierce.“ The bands Deep Sun and Burning Witches also have personal connections: Destruction guitarist Damir Eskić, co-founder of Burning Witches, and Deep Sun keyboardist Tom Hiebaum have been friends for many years, so the paths of the two bands have crossed repeatedly.
Debora finally found another important voice in Ambre Vourvahis from Xandria. „Ambre is the singer of one of the most successful symphonic metal bands around right now. Her voice harmonizes incredibly well with mine – it was almost a given that she would join us.“
The alliance was rounded off by Dani Nell from DevilsBridge. „I’ve known Dani since the Edenbridge tour in 2024, which we did together. She brings both emotionality and modern hardness – exactly what Fierce needed to gain depth and dynamism.“
Thus, Debora’s original album track became an anthem that unites four singers: a powerful musical statement for solidarity, diversity, and female power in metal.
