Mkay. Although I agree that Jimmy Hendrix is a guitar God ...
WHERE THE HELL IS LED ZEPPELIN IV ? This is arguably the finest crafted guitar album ever , but yet ... it isn't even in mojo's top 20 list . WTF? Where is You Had It Coming by Jeff Beck or  Derek and the Dominos Layla & Other Assorted Love Songs ? I also have to mention ACDC's Back in Black . WHO ARE THESE JOKERS AT MOJO MAGAZINE ANYWAY ? 
Did I forget any great guitar albums that SHOULD be on this list ?
