I am not sure is it is "interesting".
It is more complex than either ORTF (et al) or Decca, but in my view not unduly so. We often use additional "ambiance" mic's, in my case they simply have more clearly defined job description.
If you listen to Decca and Deutsche Gramophone classical recordings they are almost the opposite, spatially. And neither is all that realistic compared to a first third center seat in (say) the Barbican. Each gets some aspects rights, at the expense of others.
Decca is spacious, realistically so, but the ensemble is amorphous, almost more so than from the boxes in the back.
DG is extremely clear and instrument placement is precise, but mostly en miniature, it sounds small, it fit's into my 300 sqft front room in a semi-terraced victorian house in London..
What I was seeking was to marry these two, to have realistic spaciousness and a feeling "they just removed my walls and transported me into a concert hall" that Decca excels on but with a highly resolved and instrument specific sound stage like DG.
Hence this combination of minimal directional stereo center and spaced omni in the back.
As super bonus, it's all completely mono compatible, which was something that mattered a LOT back in the 80's of the last century of the last millennium.
