Ummm.... not sure if serious... but they used a hologram of hide from the 1993 show during the Art of Life performance in 2008. It looks like he's there in the video as it's edited to be that way. When you see shots from far away, you'll see it's just a smokey hologram on stage. What made you think these are from the same show? The other members, including Yoshiki don't even look remotely the same. LOL
The problem for me is that I wasn't watching the other members but looking at Yoshiki in this particular video. I did notice the hologram at around 8:14 into the video but going back and watching, again, from :29 up until that point, I don't believe that's the hologram. I think whomever made this video inserted the part of hide playing from the 12 Dec 1993 show up until the 8:14 mark, then showed the hologram after that. If you look at hide's image before that time, the image is solid and he appears to be playing and moving in exactly the same position, fingering, body movement, etc, as in the 31st Dec, 1993 show and is not semi-transparent like in the hologram.
Oh well, I tried. LOL.
So - Yoshiki did not pass out on 12 Dec, 1993?
And I wasn't aware they used a full body hologram of hide, only one of his head and shoulders. Ooops! I have a lot to learn, I guess. LOL
