Best sounding CD of Brass?

I attended a performance of an unamplified brass jazz band the other night and wondered what CD in my collection (I have around a hundred jazz CD's) would be best to evaluate my system compared to what I heard live. I don't have one, so I turn to you, wise Gonners, to tell me what CD of brass music SOUNDS the closest to live instruments? I don't really care about classic performances, as this will be an analytical tool. Strictly sound, especially catagories such as dynamics, clarity, tonal characteristics, frequency, to a lesser degree soundstage and image.
