Dave Grohl, for me, is always an interesting figure. First, he's first and always a drummer by heart! Of course his famous drumming time was with Nirvana that in my youth time (yes I was young once) bring different colour for the regular music I listen to. Mind you I listen to my dad's old collections, mostly were classic rocks (and heavy metals).
Two, Foo Fighter man! What's not to like from this band?! I might not know everything about them, because to be honest I want to hear their musics not who are they sleeping with at the moment and what brand they wears or some other sh*ts like that.
However, the biographer I think spent too much time talking about his researches regarding the band and the man: the albums, side projects, details on gigs or festivals they attended bla bla bla. I want more, I meant really really more, insights of his crazy mind not his schedules!
