I think the "Zarathustra" and the "Gaite" were recorded within days of each other,and released on the same day. Some speculation here: 1952,puts us at the tail end of the binaural era,which dates back to the experimental Bell/RCA/EMI recordings from the 30s.Considering our writer bought these in Morocco,a French colony,surrounded by British ones,they obviously sold stuff from these two colonial powers.RCA and Mercury were both doing binaural recordings at the time,with Stokowski,Kubilek,and Heifitz. http://www.classicalsource.com/db_control/db_cd_review.php?id=4091&PHPSESSID=415f39591cf5226e142a588afdb818c6 Not to mention the famous Heifetz,Bach which some of us like,and some of us don't.All were under the HMV umbrella.HMV,Echophone,or somebody could have made commercial units as early as 1952. Someone here probably knows all about this stuff. Roger Tom Fine <[log in to unmask]> wrote: I'd be interested to know what's on them and who released them. I do not believe you'll find that they are in fact 2T stereo. They are likely half-track (2-sided) mono. If they are stereo, it would be very interesting to know who put them out as in 1952 only a few people were experimenting with 2-channel stereo recording of music. No major labels yet, although I believe RCA started making 2T masters in 1954 or even 1953 -- I think Zarathustra with Reiner was the first 2T session. -- Tom Fine ----- Original Message ----- From: "Jack Palmer" To: Sent: Sunday, April 08, 2007 12:29 AM Subject: Re: [ARSCLIST] commerical reels history (was Boston Pops question) > I bought my first 2 track tapes for my reel recorder/player in the Base Exchange in > Sidi-Slimane, Morocco in 1952.
