No doubt. I saw them headline on the Warning Tour and to this day I think Child of Fire is the best vocal performance I've ever seen live. The place was only half crowded but everyone there knew all the words to every song except Prophecy. During Deliverance the crowd was almost as loud as Geoff.
I agree those are 2 of the 10 best albums of all time.
1/28 - Machine Head
3/3 - Hell Yeah
3/31 - Coal Chamber & Filter
