I'm
loving this thread. And I hope you won't take offense,
@sjcorne, if I say that we need more of the sort of careful, analytical listening that's behind this sort of geekiness. (If I had more time and ambition,
I would be one of those geeks!)
In fact, somebody, not necessarily you, should build a searchable, sortable online database that tracks this kind of thing for
all of the instruments (and vocals) in a given surround mix. And then some clever programmer could write a bit of software that takes the data from a given album and, at the press of a button, generates a 2-D visual surround map of that album. (Maybe even track by track!) Anybody here have the chops for this?
As a musician, I've always dreamed that somewhere, sitting in a vault, all of my favorite heros' original studio music source masters were safely stored on 16, 24, 32 (or more) track tapes or files in their most perfect and highest possible resolution and condition, just waiting to be made available to me or anybody in an easily retrieved discrete chain of free access.
Then, I could listen to each musician playing their original part in any combination and learn how it was done.
I could also re-arrange everything to my taste for my listening pleasure.
As a drummer, I believe the rythym section carries the whole piece like a solid foundation, and therefore the bass, rhythm guitar and drums should be spread naturally throughout the sound field, and NOT each separately shuttled off into a corner.
For me, I like the kick to be predominantly on the floor and all around, everyone taps their feet or dances to the kick drum, then with the snare front and center, hihat slightly left, floor toms more to the right... for those bombs, ride should be high center right, crash above the floortoms, bass guitar should be inescapably locked in balanced acoustic counterpoint and woven deeply into the drum soundfeild for a rock solid foundation.
The singers, lead guitars and other soloists can hang spatially distinct from the rhythm section, but all groups depend upon an ability to hear what the drummer and bass player are doing at all times, and I think it is critical to deliver that level of truth and realism to the audience.
One optional difference I see is that the drummer's L&R can be swapped because everyone else hears the Hihat and floor-toms on the reversed side from the drummer who sits facing out toward the audience.
I also think it is great when you can hear for example the reflected echoes (occurring after snare rim shots) bouncing milliseconds later off the room to give the impression of space.
Spatial Psychoacoustics can and should play a MAJOR role!
When you listen to Steve Gadd's latest jazz release, also Billy Cobham's Drum n'Voice Vols 1-4, you can easily hear how a lead drummer with expansive top tear recording experience can arrange the sound in each channel (be it stereo or quad) to build a cohesive sound with superb musical clarity.
