What concert or music DVD's are worth having?


My brother and his wife (how own a copy of every DVD ever made) make fun of me because the only DVD's I have are music videos or concert footage.

I have:
Alice Cooper 'Welcome to my Nightmare' which is not very good.

Jethro Tull 'Living with the Past' worth owning!

Midge Ure I forget the name, but it's pretty good

Queen, very dated

I think there are more but I'm not sure. What concert DVD's do you have that are worth owning?

Walter Trout and the Radicals - Relentless

All new material live at the Paridisio in Amsterdam. Great music, intimate setting and excellent sound. It even has a stereo PCM format in addition to Dobly Digital 5.1 and 2 channel.
The early Led Zeppelin double DVD! Disc one, which covers a lot of the first 2 or 3 records, is AMAZING! (and the sound quality's good)
