The performance itself was a heartwarming highlight of the festival, featuring the late Taylor Hawkins, the band’s longtime drummer, who graciously stepped aside to allow Harper to take his place behind the kit. Hawkins remained on stage to provide vocals while the band played Queen’s iconic anthem, We Will Rock You, which was the first song Harper had ever learned to play. Harper displayed incredible poise and confidence for her age, successfully executing the song while her father looked on with visible pride. The collaboration served as a poignant example of the next generation engaging with the rock legacy established by their parents.

The musical involvement of the Grohl children continued beyond the Iceland festival. In 2018, both Harper and her sister Violet appeared on stage with their father during the Notes and Words benefit concert. This event, which aimed to raise funds for the UCSF Benioff Children’s Hospital in San Francisco, featured Harper on drums and Violet providing vocals, further cementing their roles as budding performers. It was a clear demonstration of their growing comfort with live performance.

As of the latest reports, the Grohl family continues to be associated with various musical endeavors, and the public remains interested in whether these early performances might lead to further artistic collaborations. The footage from the 2017 Secret Solstice Festival remains a frequently cited example of the family’s shared passion for music and the enduring influence of Dave Grohl’s career on his children as they grow, leaving fans to wonder what musical path they might choose in the future.
