Machine Head question
So I have a question about Machine Head that maybe one of you veteran metalheads here can answer. So on the list of the many albums I have not had a chance to listen to, my older cousin let me borrow her two Machine Head CDs The Burning Red and The More Things Change... She says Machine Head is her favorite band.
Well anyways now I look at their first two setlists on the Mayhem tour (from setlist.fm) and nothing from either album. Now for my questions: Are Machine Head known to completely skip those two albums in their sets? And is my cousin missing a lot of good music by them off the albums she doesn't have of theirs?
