Dave Grohl has spoken extensively about his admiration for classic rock figures and the formative influence of collaborating directly with musicians he once only admired from afar. Through partnerships with artists including members of Led Zeppelin, Grohl gained insight into how his heroes approached their craft and conducted themselves within the industry.

When discussing his personal heroes, Grohl specifically highlighted Brian May as standing apart for his character and kindness. Despite co-creating some of rock's most recognisable songs, May has reportedly remained notably grounded and accessible—a distinction Grohl described as rare in an industry typically dominated by ego-driven personalities. Grohl framed May's greatest legacy not as his musical innovations alone, but as his ability to demonstrate how accomplished artists can maintain integrity and generosity toward others.
