Part of Grohl’s enduring appeal is his enthusiasm as a fan. Even after decades of success, he still speaks about music with the same excitement and curiosity that first drew him towards a life in rock and roll. As a child of the late 1960s, he rose to cognition just as the world recovered from the loss of The Beatles.
