What concert or music DVD's are worth having?

Grateful Dead-View from the vault series
Nine Inch Nails-All That Could Have Been
Steely Dan-2 Against Nature
James Taylor-Live at the Beacon Theater
Roger Waters-In The Flesh

and many others...I like you have more concert/music videos than movies...a lot time I just cue them up and then turn off the t.v. just so it can sound even better.

Ellery

Roxy music
Peter Gabriel
Paul Simon

For Reference -
Stop Making Sense is the standard for all concert videos.
Steely Dan - Two Against Nature - check out Donald Fagan's canine's.
Roger Water - In the Flesh - good Pink Floyd production.
Eagles - Hell Freezes Over - cheesy music but great A/V production
Band - The Last Waltz - a classic
For Fun -
Rolling Stones - At the Max - the original IMAX movie
Rolling Stones - 4 Flixs - 3 venues of their concerts
Led Zeppelin (3 disc Set) -a classic
Sheryl Crow - Rocking the Globe Live

I just started collecting this year after setting up my first home theater. Here's the concerts I have and like. Obviously it's gonna depend as much on your taste in music and bands, but the shows in the "best" group are all excellent. I have a couple of DVDs that the shows or the recording just are too poor to even recommend

Best:
Concert for George (this is an unbelievable concert)
Allison Krauss & Union Station Live
Peter Gabriel - Growing Up Live
Cowboy Junkies - Open Road (this is only Stereo/Pro-logic)
Neil Young at Red Rocks
Metallica S&M

above are sort of in order preference - but all great

Also good:
Steve Hackett: Somewhere in South America
King Crimson - Eyes Wide Open
Procol Harem Live

Jon Fogerty : Premonition
Eagles : Hell Freezes Over
Fleetwood Mac: The Dance

I'm adding not repeating excellent recommendations already given by other fellow Audiogoners!!
