In his 20 bands that matter story, Hilburn describes a band perfectly in his opening statement then leaves them off the list. The band is Midnight Oil.
The Oil's music has done more to make people aware of environmental issues, conservation and social injustice than any band ever and they do it in a ripping sort of way.
He should make the Oil No. 2 and make a new list of the top 50 (so he has somewhere to put Guns N' Roses).
