Best Concert DVD


Now that I finally have a pre/pro (Krell Showcase)that does justice to music, I have been snapping up concert dvd's.

Now I'm looking for recommendations. Which concert dvd's do you find exceptionally well done in terms audio and video fidelity? Which ones were the best in terms of the artist's performance?

Billy Preston (winner go round in circles)??
For those who care - "Will it go round in circles"
That's kind of like the older Brownsville Station song
"Smokin in the boy's room"

The last line of the chorus is ....smokin ain't allowed in school.
A friend of my wife's in college thought it was....smokin in the lounge is cool!

I get a kick out of these.

Various Artist / Best of "Live at W.54 th Street" PBS music series. Great audio tracks covering a wide range of music genres.
Elton John at Madison Square Garden, I think its called 1 night only.
I recently saw something called "G3" for you electric guitar fans. It had either Joe Satriani or Steve Vai or maybe both
