Over the weekend, I stumbled on a treasure trove of information about the famous Decca Recording Studios, based in London, responsible for two of the initial 10 TP titles (the ones whose licenses run out in a couple of weeks.) It is in the form of an over 1500 page long essay completed in 2009, documenting almost all of the classical music recording sessions from the late 1920's to 2008. This includes the golden era of Decca stereo analogue recordings from the mid 1950's until about 1980. The website which is from Imperial College in London
http://www.charm.rhul.ac.uk/index.html (thanks Steve) gives a link to the downloadable files - the complete Decca file is the one I downloaded. You can also see other files including the recorded history of the Academy of St. Martins in the Field and the London Symphony as well as other documents. The Decca file is quite large, over 5 MB. The core of the analogue LP era is in the file called Decca3 (part of the total file) and is still some 504 pages long and 2 MB.
In my comments on the TP issue, I noted that I thought the Hindemith recording was the better than the Bruch sonically. Now I know why they sound different. Note that in the file notes, that the two were recorded in two different venues, with different engineers, and different conductors. Hindemith himself conducted his concerto, while Jasha Horenstein was brought in to conduct the Bruch and that originally there was to be a different coupling with the Hindemith - the famous Mozart Sinfonia Concertante for violin and viola. It looks like that sometimes things happen during a recording session and it isn't always magic. Maybe Paul, Romo or Dan can comment on recording sessions they have done.
Here is the file on the Oistrakh-Hindemith recording:
