I already had a number of IG CDs when I found this Gold Disc in the music store. I bought it on the spot and ran home to play it on my CD player. I played it over and over and swapped the original silver CD with the Gold CD to see if I could tell a difference, and I couldn't.
The CD comes in a cool cardboard/paper sleeve that the jewel box fits in, but other than that, and the gold color (and 24kt gold content) of the disc, there is absolutely no difference... especially in the sound.
When you turn the volume up all the way on both the original, you hear the pops and squeaks as the guitarists hands and fingers move along the strings. The gold edition of this disc still includes these pops and squeaks. They weren't removed, and if this gold version is supposedly "re-mastered" from the original, it must have been re-mastered for the hearing range of bats, because I can not tell the difference.
If you're into collecting everything they've ever done, or you don't already own the original version of this CD, this is a good buy... the gold version will supposedly last longer, but it's not like you're going to be saving the silver version for your great-great grandchildren. Unless you leave your CDs on the dashboard of your car in the hot sun, the silver version should last past your life time anyway.
