I need a live great recording


I've come to realize that there's no better way to hear what your system is capable of than a LIVE RECORDING.

I need your help.

Suggestions for 'live recordings' on cd that can really expose a system's strengths and weaknesses.

I almost forgot, Dave Alvin and the Guilty Men, "Out in California", a fantastic live rockabilly cd with very good sound and intense energy.
If you like bluegrass I recommend:

Alison Krauss + Union Station "Live"
The Johnson Mountain Boys "Live at the Old Schoolhouse"

Several posters recommended eric claptons unplugged...I agree, and the dvd is dramatically better soundwise than the cd..try it and see..you wont be sorry
Benjamin Zander leading the Boston Philharmonic Orchestra in STRAVINSKY's Sacre de Printemps on Pickwick 1990 (now Carleton Records), live at Jordan Hall, Boston. The awaited revisit performance two years ago wasn't as good (alas).
This was the first recording of the Sacre at original tempo, as well, and has astonishing musicality and tension. You WILL be in the hall, on the edge of your listening chair in the Sacrificial Dance. This is a favorite gift CD of mine after I set up a budget system for a friend. A jaw-dropper everytime. Do NOT have an espresso with your dinner guests if you're going to play this, and plan to go for a walk afterwards to shake off the transferred chi!
Here are some of my best-sounding live pop/rock CDs:

1) James Taylor "Live (1992)"
2) Elton John "Live in Australia"
3) Eric Clapton "24 nights"
4) Grateful Dead "Without a Net"
5) Bela Fleck/Flecktones "Live Art"
