Last summer I made some Blumlein test recordings in Sierra Valley, CA.
My recollection of the recordings was the imaging seemed off since
there was no frontal "sound stage" it is basically all around.
Specifically I remember when anything flew front to back it seemed to
switch sides as it crossed over the mic array. I think there is an
example of this in track the second example below.
Here are two unedited examples:
