I need a live great recording

Dianne Schuur & the Count Basie Orchesra. Even though it's a 1987 GPR digital master, absolutely incredible bass and can be played at extreme volume levels with very little if any grain. It your room is treated properly you will enjoy an incredible jazzy big band performance with sweet vocals.

Bill Evans "Sunday At The Village Vangard" and "Waltz For Debbie" are among the best records in Jazz history.
I love Keith Jarrett's At the Blue Note box set (worths the money).
Something newer and very interesting is Directions in Music: Live at Massey Hall from Herbie Hancock, Michael Brecker and Roy Hargrove (unbelievable trumpet).

It's from Mapleshade, and about the only one of their offerings I continue to enjoy, Clifford Jordan Quartet, "Live at Ethel's."

a similar thread has been done before but I will chip in with:

Bravo Brubeck! very natural piano tone

and

I agree with: Eva Cassidy Live at Blues Alley, the atmosphere of a live venue is very apparent.

Rippingtons "Live in LA" and for a night club arena, Zachary Breaux "Groovin, Live at Ronnie Scotts"
