I was reading the history of Metallica and came across the NWOBHM. An acronym so funny you have to say it twice. Saxon is the leader of the New Wave of British Heavy Metal according to wikipedia (Iron Maiden, Def Leppard). So they have been a major influence on a lot of bands, including Metallica, Megadeth, Dream Theater, Testament, etc. I was on a seventies tour the day I bought this and the last two records.
When I had a friend visiting who was very much into metal, she was browsing through my collection and exclaimed wow, you have Saxon! Sometimes the value of records can only be seen by the reaction of others. I think I listened to this record three, four times. It is not really my thing, but I get that it is a major influence.
