Thanks to this thread, I listened to Slip of the Tongue for the first time in years today. Way better than I remembered. I was really disappointed when it came out.
I prefer the original mix of "Judgment Day" to this one--Vai's playing is impressive on this alternate version, but the original is more distinctive and the layering at the end is more effective.
However, this new mix of "Fool for Your Loving" is way better and should have been on the original album.
