Re: [ARSCLIST] Early Stereo 1881 and 1931 (Was - Dynadoodoo
From: Patent Tactics, George Brock-Nannestad
Mike Gray's transcription of the recording sheets made me realize that I am
not the born discographer - I had made errors in my listing (I had misread my
Before bringing the corrected version I would like to point out that I can
only vouch for the existance of vinyl pressings as listed by me. I have no
idea whether the remaining recordings listed on the recording sheets and
transcribed by Mike have ever been pressed in vinyl, or even whether the
metals still exist. Also, I would like to point out that the matrix numbers
given by me are the way they are stamped in the metal, and that is different
from the listing in the recording sheet.
Another note: the recording sheets give dry facts. In the book by Robert
Charles Alexander: "The Inventor of Stereo. The Life and Works of Alan Dower
Blumlein", Focal Press, Oxford 1999, there is a narrative putting names to
the collaborators of Blumlein in the experiments, and they are individually
discussed, but not necessarily providing more than the dry facts for each
case. This is on pp. 77-80. The whole chapter about binaural recording is
from pp. 60-77.
