Wait - no one has mentioned the obvious. If the quartet is playing to a pre-recorded track, they are going to have headphones, and therefore, they will presumably be listenting to each other's instruments through the headphones also.
This may put some limitations on how you set up the mikes. You'll probably need one set optimized for performer monitoring, and then the main set to actually capture the performance.
Or have i missed something?
Jeff, post 11: "Now I have forgotton that they might be playing to a pre recorded track, is that right. So if you do an M/S recording you will have to do a temporary decode live and send it to their cans as well as the music obviously. If you get the balance right there (slightly more quartet so they can hear each other well) then you should be OK too. When I have recorded quartets playing to tracks sometimes micing them individually might be the better option."
But yes, this is important to prepatory work done and will add other dynamics that may affect how well the quartet plays depending upon their experience with this type of setting. Might be better to keep it simple s***** or not and cover all your bases and be able to provide a mix they can live with in the cans?
