Aside from the fact that both Yngwie Malmsteen's and Cacophony's albums weren't instrumental (sadly, in the case of Cacopohony...imo) I like your list. I ignore the order though. I shall now listen to John 5.
Btw...you may want to add some album by Jarle H. Olsen. Joey Tafolla's Out Of The Sun, Christian Muenzner's Timewarp are others to consider.
