thank you very much.

I recorded four shows over the past week. I'm still sorting, and finishing. I finally got around to listening to the discrete two channel stereo tracks, and this one is, imho, quite a stunner.
It is done in what is referred to as the Boundary Layer Effect stereo technique; two omnidirectional mics placed in such a way as to be just barely higher than a hard boundary surface, like a rear wall of a hall, or, in this instance, tight to the hard drywall face of the balcony; outer face.
The theory is that the first incoming wave of sound impacts the hard surface layer, where it impacts that surface, and then rebounds off of it, in the first reverberant wave, room reverb cycle, or echo.
With the microphone mounted in close relation to the hard surface boundary layer, it gets excited by that first impact of sound. Then in an instantaneous, or, coincidnetally timed moment, the first reverb cycle leaves the hard boundary layer, and, re-impacts the already excited mic capsule, giving a presence boost that is somewhere around 2 or 3dB of presence boost gain.
That first reverb cycle is now furthering itself into the room, moving away from the microphone capsule, and goinf into a negative phase relationship with the mic capsule, which drastically reduces the reverberation cycle into its own decay cycle, with each subsequent cycle being less and lesss apparent.

With all of that said,... I give you this same concert in Boundary Layer Effect, pure, glorious, two channel ambient stereo recording.
This hall and this technique are magical together
