Thanks for the reply.
I am indeed going to put my camera 10 meters from the band in the center line (gorlillapod on the railing or something) and not move the camera. Now I really am interested in what type of mic would be good for this? As you mentioned a camera like that is the one that gets the best sound.
If I change my mind a bit and intend to pan or tilt the camera, I will have another gorillapod for the mic for it to still not move around, but as I don’t have a decent video head or rig or even image stabilization, I will most likely simply not touch the camera at all.
