Concert stage layout -- who made who?


Last night I was visiting a friend to listen to his SET setup. It sounded very nice - kinda the polar opposite philosophically from my own system... but anyway.

We were listeing to Bave Brubeck's Time Out. I wondered after listening for a while about the soundstage placement of the musicians. The drums were on the right (in some tracks) along with the keyboards. The clarinet(?) and flute seemed to be in the left of center portion of the stage (that's not a political comment) while something else (I can't remember what it was) was placed far off to the left.

Generally nowadays with Jazz/folk/rock the drums are in the center/back, while the star/singer is in the front while the other status instruments are immediately to the right and left of the singer/star. Okay, so here's the question: did the layout of the soundstage dictate where people stood on the stage, or did the stage dictate the soundstage?

First of all Nate, it's BABE Brubeck's Time Out, not BAVE Brubeck.

I don't see how anyone can make such a silly error.
Given recording techniques at the time that I saw when I was young and that you can see in pictures in some of the record jackets (for example, check the LA4's Pavanne album), the recording was made in a studio, and the soundstage you hear is in all likelihood artificial. Usually there were acoustical screens (not so high as to prevent them from seeing and hearing each other) between the musicians in the studio, with the drummer generally in the back (I usually have Joe Morello's drums toward the left in my system, on at least Take Five) and the others set up as they preferred to perform the music for the recording. Each instrument was individually miked on its own track, and the screens were intended to keep the sounds of one instrument from getting through to the tracks of the other instruments. Their final placement in the soundstage on the record was really in the hands of the producer, therefore. I would also say that for rock especially and jazz, except in the case of purist recording companies such as Chesky or live recordings, today's soundstage for those genres is the same, in the hands of the producer--hell, many rock albums have tracks cut individually and blended on the console/computer, rather than the whole band performing together.
