Hard to rate these but Southern Nights 5 although sound lacking a touch [but it's a soundboard]
Dragon Heart the sound is good but concert not quite cutting the mustard 3-4
Takin Tahoe is a flat concert for me -2
Closing Night is a very interesting concert that has to be played a lot to be appreciated and is one of my own personal favourites.
It's worth checking out all the reviews you can find about it.The site called DESERT STORM has many reviews about this concert worth investigating before you buy.
The fantastic book, ELVIS: CAUGHT IN A TRAP is an essential companion to this concert and features stunning pics and info from Elvis's Vegas 73 concerts.
I'll rate it 5.
