As the lead guitarist and vocalist to two of the more quietly influential acts of the 80s and 90s with both the punk rock of Hüsker Dü and the more melodic Sugar, Bob Mould has continually contributed earnest and often groundbreaking music to the rock landscape. This also includes perhaps his most instantly recognizable composition, one which has entered into millions of homes on a nightly basis for nearly 16 years and 2,200 episodes. Without Bob Mould's music, there quite simply would be no Foo Fighters, as his influence is pretty plain to hear to even the most untrained ear even when he's not working directly with them. As time has encroached upon Mould the way it does for all of us, he's adopted a far more paternal look than in the early 80s and 90s, complete with a full and immaculately groomed white beard, which has pretty much only served to make him cooler.
