well to be honest.. jumping from studio audio into generically recorded live audio just won't sound good like that.
but i am curious... the showstop doesn't sound like rehearsal cd.. it sounds like actual park showstop just because it's missing a lot of the higher cymbals and such... Did you do an induction recording for it? And if so... why even do the live audio parts (then again if the speaker you can record from isn't where beauty and the beast showstops then it's understandable...)
I'd be curious to hear what you did manage to get though. I've done a couple mixes myself, a shorter 16 minute one that's been passed around and a longer 30 minute one for the video I did.
