I would think it be important that Alien Love Secrets by Vai be on this list and one of the top runners. Between Die to Live, Boy from Seattle and Tender Surrender, those are three of the most perfectly executed, unique, tasteful, gorgeous songs ever written. The CD really only has one subpar track in Kill the Guy with the Ball, everything else is innovative and amazing. I don't think there is any other guitar album with close to as much quality with so much diversity. Perpetual Burn has a couple of amazing tracks, but a lot of it is just filler, and Rising Force is much the same way. Those are the two top aside from ALS in my opinion, and Far Beyond the Sun will always be a fav of mine, as will Altitudes, but as an album, I think ALS takes the cake
